XC9519 Series ETR0710-009 Dual Output Step-Up/Inverting DC/DC Converter ■GENERAL DESCRIPTION The XC9519 series is a 2 channel (step-up and inverting) DC/DC converter IC. One DC/DC converter is a step-up DC/DC and the other is an inverting DC/DC converter. The step-up converter compares a built-in reference voltage 1.0V to the FBP voltage (accuracy ±1.5%) and a positive output voltage can be set freely with the external components up to 18V. The inverting DC/DC converter compares a difference between a reference voltage and the FBN voltage (accuracy ±1.5%) to the GND, then a negative output voltage can be set until -15V with the external components. With a 1.2MHz frequency, the size of the external components can be reduced. As for operation mode, the device can be selected to use PWM control or automatic PWM/PFM switching control by the MODE pin. In the automatic PWM/PFM switching control mode, control switches from PWM to PFM during light loads. The series is highly efficient from light loads through to large output currents. In the PWM control mode, noise is easily reduced since the frequency is fixed. The control mode can be selected for each application. The soft start and current control functions are internally optimized. During stand-by, all circuits in the IC are shutdown to reduce current consumption to as low as 1.0μA or less. The device includes a gate control pin for the P-channel MOSFET which is used for a load disconnection at the stand-by mode. The GAINP and GAINN pins are used for loop compensation in order to optimize load transient response. With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when input voltage becomes 2.2V or lower. ■APPLICATIONS ■FEATURES Input Voltage : 2.7V ~ 5.5V ●AMOLED Output Current : 500mA @V =3.7V, V =5.0V, V =-5.0V IN OUTP OUTN - Smartphones Positive Output Voltage : 4.0V (*1) ~ 18.0V (accuracy ±1.5% @25oC) - Tablet PCs Negative Output Voltage : -15.0V (*2) ~ -4.0V (accuracy ±1.5% @25oC) - Automotive navigation systems Oscillation Frequency : 1.2MHz Soft-Start Circuit Built-In : Step-up DC/DC converter 2.5ms (TYP.) ●CCD image sensors : Inverting DC/DC converter 2.2ms (TYP.) - Surveillance cameras Protection Circuits : Over Current Limit (Integral Latching) ●e-paper Short Protection Latching UVLO -e-Books Thermal Shutdown Over Voltage Protection Function Addition : Control Pin Load disconnect Pin Phase Compensation Pin Ceramic Capacitor Compatible Operating Ambient Temperature : -40℃ ~ +85℃ Package : QFN-24 Environmentally Friendly : EU RoHS Compliant, Pb Free （*1）V ≧V + 0.2V (V :Positive output voltage range) OUTPSET IN OUTPSET （*2）V - V + V ≦21.0V IN OUTNSET FN (V : Forward voltage of SBD ,V : Nagative output voltage range) FN N OUTNSET ■TYPICAL PERFORMANCE ■TYPICAL APPLICATION CIRCUIT CHARACTERISTICS V =5.0V, V =-5.0V, I =I OUTP OUTN OUTP OUTN CLP, CLN=4×4.7μF, LP, LN=3.3μH (VLF5014S-3R3M2R0), SBDP, SBDN: CMS03 LP SBDP VOUTP 10P0-ch MOS: EMH1303, RZP=7.5kΩ, CZP=4.7nF, RZN=130kΩ, CZN=0.47nF CFBP V ="H",V ="H" SWP LXP VOUTP RFBP1 ENP ENN P-ch MOS BSW FBP RSP CLP 80 %) PVIN VREF AVIN RFBN2 CL_VR RFBP2 EFFI( 60 3.6VVIN= 4.4V ENP XC9519 FBN cy: 2.7V VIN CIN_SW CIN_P CIN_A ENN MODE RFBN1 cien 40 AGND VOUTN VOUTN Effi PGND LXN SBDN 20 PWM/PFM (VMODE="H") PWM (V ="L") GAINP GAINN CLN MODE 0 RZP RZN LN 0.1 1 10 100 1000 CZP CZN Output Current:I , I (mA) OUTP OUTN 1/38

XC9519 Series ■OPERATIONAL EXPLANATION The XC9519 series consists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, driver transistor, current limiter circuit, short protection circuit, UVLO circuit, thermal shutdown circuit, over voltage protection, load disconnect control and others. (See the block diagram below.) By using the error amplifier, the FBP (FBN) pin voltage is compared with the internal reference voltage. The error amplifier output is sent to the PWM comparator in order to determine the duty cycle of PWM switching. The signal from the error amplifier is compared with the ramp wave from the ramp wave circuit, and the resulting output is delivered to the buffer driver circuit to provide on-time of the duty cycle at the LXP (LXN) pin. This process is continuously performed to ensure stable output voltage. The current feedback circuit monitors the driver transistor current for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when using a low ESR capacitor such as ceramic, which results in ensuring stable output voltage. In terna l O N/ OF F Co ntroller * Diodes inside the circuit are an ESD protection diode and a parasitic diode. 9/38

XC9519 Series ■OPERATIONAL EXPLANATION (Continued) <Reference Voltage Source> The reference voltage source provides the reference voltage to ensure stable output voltage of the DC/DC converter. <Step-up DC/DC Converter Error Amplifier> The step-up DC/DC converter error amplifier is an amplifier for output voltage monitoring. The FBP pin voltage is compared to the reference voltage. When a voltage lower than the reference voltage is feedback to the FBP pin voltage, the output voltage of the error amplifier goes high. External compensation of the error amplifier frequency characteristic is also possible. <Inverting DC/DC Converter Error Amplifier> The inverting DC/DC converter error amplifier is an amplifier for output voltage monitoring. The FBN pin voltage is compared to GND. When a voltage higher than GND is feedback to the FBN pin voltage, the output voltage of the error amplifier goes high. External compensation of the error amplifier frequency characteristic is also possible. <Ramp Wave Circuit> The ramp wave circuit determines switching frequency. The frequency is fixed 1.2MHz internally. Clock pulses generated in this circuit are used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits. <UVLO Circuit> When the AVIN pin voltage becomes 2.2V or lower, the driver transistor is forced OFF to prevent false pulse output caused by unstable operation of the internal circuitry. When the AVIN pin voltage becomes 2.4V or higher, switching operation takes place. By releasing the UVLO function, the IC performs the soft start function to initiate output startup operation. The soft start function operates even when the AVIN pin voltage falls momentarily below the UVLO detect voltage. The UVLO circuit does not cause a complete shutdown of the IC, but causes pulse output to be suspended; therefore, the internal circuitry remains in operation. <Thermal Shutdown> For protection against heat damage of the ICs, thermal shutdown function monitors chip temperature. The thermal shutdown circuit starts operating and the driver transistor will be turned off when the chip’s temperature reaches 150 oC. When the temperature drops to 130 oC or less after shutting of the current flow, the IC performs the soft start function to initiate output startup operation. <PFM Switch Current> In PFM control operation, until coil current reaches to a specified level (I , I ), the IC keeps the driver transistor on. In this case, time PFMP PFMN (t ) that the driver transistor is kept on can be given by the following formula. ON tON = L ×IPFMP (IPFMN) / VIN < PFM Duty Limit > In PFM control operation, the maximum duty cycle (DTY ) is set to 50% (TYP.). Therefore, under the condition that the duty increases LIMIT_PFM (e.g. the condition that the step-up ratio is large), it’s possible for the driver transistor to be turned off even when the coil current doesn’t reach to IPFMP (I ). PFMN 10/38

XC9519 Series ■OPERATIONAL EXPLANATION (Continued) < C Auto-Discharge Function > L This function enables high-speed discharge of the charge on the output capacitor (C) when an L level signal is input to the ENP (ENN) pin by L means of the internal switch between the VOUTP pin and AGND pin (between the VOUTN pin and AVIN pin). This function makes it possible to prevent malfunctioning of applications caused by charge remaining on C. L The discharge time is determined by the C discharge resistance (R ) and C. Ifτ(τ= C × R ) is the time constant of C and R , the L DCHC L L DCHG L DCHG equation for the output voltage discharge time can be obtained from the following CR discharge equation. ｔ=τln（V / V） OUTSET V: Output voltage during discharge V : Output voltage OUTSET t: Discharge time τ: C×R L DCHG [Example] When the set voltage (V )=5.0V, C =18.8μF, and the C discharge resistance (R )=200Ω (TYP.) of the DC/DC Converter, the OUTPSET LP L DCHGP discharge time t from the start of C high-speed discharge until the output voltage falls to 1.0V can be calculated as follows: L ｔ=τln ( V / V )= C ×R ln ( V / V ) = 18.8μF×200Ω×ln ( 5.0V / 1.0V ) = 6.05×10-3 s = 6.05 ms (*1) OUTPSET LP DCHGP OUTPSET (*1) Calculated with I = 0mA OUT <Internal OSC Timing Chart> The step-up DC/DC Converter and the Inverting DC/DC Converter are switching synchronously based on one internal clock. The phase of the step-up driver on timing for the DC/DC Converter is shifted to completely opposite position (180 degrees different) upon the phase of driver on timing for the Inverting DC/DC Converter. 1.2MHz Internal OSC Inductor Peak Current Boost_I LX 0A Inductor Peak Current Inverting_I LX 0A <Overvoltage Protection> Overvoltage protection monitors the output voltage V (V ) using the FBP (FBN) pin voltage, and prevents the output voltage V OUTP OUTN OUTP (V ) from rising too far above the set voltage. In particular, fluctuations in the load cause the output voltage to rise, and when the FBP (FBN) OUTN pin voltage reaches the overvoltage protection detection voltage, the driver transistor of the step-up DC/DC converter (inverting DC/DC converter) is turned off to hold down the rise of output voltage. When the output voltage falls after overvoltage protection detection, normal DC/DC converter operation resumes. The output voltage V that is detected by overvoltage protection is obtained from the following equation: OUT_OVP V (V )=V (V ) × V (V ) OUT_OVP P OUT_OVPN OUTPSET OUTNSET OVP P OVPN V (V ): Output voltage, V (V ): Detect Overvoltage Protection Voltage OUTPSET OUTNSET OVPP OVPN [Example] In a step-up DC/DC converter with the indicated conditions, the output voltage V that is detected by overvoltage protection can be OUT_OVPP calculated as shown below. Condition: Output Voltage (V )=5.0V, V =V +0.07V(TYP.) , V =1.0V(TYP.) OUTPSET OVPP FBP FBP V = V × V = 5.0V× (1.0 + 0.07(TYP.)) =5.0V× 1.07 = 5.35V OUT_OVPP OUTPSET OVP <Load disconnect Control Circuit> The Load disconnect control circuit makes it possible to break continuity between V and V by turning off the external P-ch MOS FET when the IN OUTP step-up DC/DC converter is in the standby state. 11/38

XC9519 Series ■OPERATIONAL EXPLANATION (Continued) <Current Limit> The current limiter circuit of the XC9519 series monitors the current flowing through the driver transistor, and features a combination of the current limit mode and the operation suspension mode. ① When the driver current is greater than a specific level, the current limit function operates to turn off the pulses from the LXP (LXN) pin at any given timing. ② When the driver transistor is turned off, the limiter circuit is then released from the current limit detection state. ③ At the next pulse, the driver transistor is turned on. However, the transistor is immediately turned off in the case of an over current state. ④ When the over current state is eliminated, the IC resumes its normal operation. The IC waits for the over current state to end by repeating the steps ① through ③. If an over current state continues for the integral latch time and the above three steps are repeatedly performed, the IC performs the function of integral latching the OFF state of the driver transistor, and goes into operation suspension mode. Once the IC is in suspension mode, operations can be resumed by either turning the IC off via the ENP (ENN) pin, or by restoring power. Care must be taken when laying out the PC Board, in order to prevent misoperation of the current limit mode. Depending on the state of the PC Board, latch time may become longer and latch operation may not work. In order to avoid the effect of noise, the board should be laid out so that input capacitors are placed as close to the IC as possible. (a) Step-up DC/DC Converter Limit < 2.0ms(TYP.)

In case where output is accidentally shorted to the GND OUTP OUTN and when the FBP voltage decreases less than short protection threshold voltage or FBN pin voltage becomes larger than short protection threshold voltage and a current more than the I flows to the driver transistor, the short-circuit protection quickly operates to turn off and to latch LIM the driver transistor.

XC9519 Series ■NOTES ON USE 1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. The characteristics of this IC are highly dependent on peripheral circuits. When selecting external components, refer to the specifications of each component and select so as not to exceed the ratings. Some peripheral component selections may cause unstable operation. Before use, sufficiently test operation using the actual equipment. 3. When the input voltage V is low and the output voltage V /V is high, the input current may be limited by the maximum duty limit and IN OUTP OUTN the set output voltage may not be output. 4. If the step-up ratio is high and excessive load current flows, the input current may be limited by the maximum duty limit and maximum current limit protection and short-circuit protection may not activate. 5. Do not connect a component other than C to the VREF pin. L_VR If a component other than C is connected, the output voltage V of an inverting DC/DC converter may become unstable. L_VR OUTN 6. For external components, use the components specified in the standard circuit examples and component selection methods. 7. When the input voltage V is high and the output voltage V /V is low, intermittent oscillation may occur during PWM control. IN OUTP OUTN 8.
