The device is ideal for generating output voltages up to 28 V from a dual-cell NiMH/NiCdorasingle-celldeviceLi-Ionbattery. 7.2 Functional Block Diagram SW Under Voltage VIN Lockout Bias Supply 400 ns Min Off Time Error Comparator FB - S Power MOSFET + RS Latch Gate N-Channel Logic Driver VREF = 1.233 V R Current Limit 6 m s Max + RSENSE EN On Time _ Soft Start GND 7.3 Feature Description 7.3.1 PeakCurrentControl The internal switch turns on until the inductor current reaches the typical DC current limit (I ) of 400 mA LIM (TPS61040-Q1) or 250 mA (TPS61041-Q1). Due to the internal propagation delay of typical 100 ns, the actual current exceeds the DC-current limit threshold by a small amount. The typical peak current limit can be calculated: V I = I + IN × 100ns peak(typ) LIM L V I = 400mA + IN × 100ns for theTPS61040-Q1 peak(typ) L V I = 250mA + IN × 100ns for theTPS61041-Q1 peak(typ) L where • V =Inputvoltage IN • L=Selectedinductorvalue • I =TypicalDCcurrentlimit (1) LIM Thehighertheinputvoltageandthelowertheinductorvalue,thegreaterthepeak.

TPS61040-Q1,TPS61041-Q1 SGLS276D–JANUARY2005–REVISEDMARCH2016 www.ti.com Feature Description (continued) By selecting the TPS6104x-Q1, it is possible to tailor the design to the specific application current limit requirements. A lower current limit supports applications requiring lower output power and allows the use of an inductor with a lower current rating and a smaller form factor. A lower current limit usually has a lower output- voltagerippleaswell. 7.3.2 SoftStart All inductive step-up converters exhibit high inrush current during start-up if no special precaution is made. This can cause voltage drops at the input rail during start-up and may result in an unwanted or early system shutdown. I LIM 4 The TPS6104x-Q1 limits this inrush current by increasing the current limit in two steps starting from for I LIM 2 256cyclesto forthenext256cycles,andthenfullcurrentlimit(seeFigure15). 7.3.3 Enable Pulling the enable (EN) to ground shuts down the device reducing the shutdown current to 1 µA (typical). Because there is a conductive path from the input to the output through the inductor and Schottky diode, the outputvoltageisequaltotheinputvoltageduringshutdown.Theenablepinmustbeterminatedandmustnotbe left floating. Using a small external transistor disconnects the input from the output during shutdown as shown in Figure17. 7.3.4 UndervoltageLockout An undervoltage lockout prevents misoperation of the device at input voltages below typical 1.5 V. When the inputvoltageisbelowtheundervoltagethresholdthemainswitchisturnedoff. 7.3.5 ThermalShutdown An internal thermal shutdown is implemented and turns off the internal MOSFETs when the typical junction temperature of 168°C is exceeded. The thermal shutdown has a hysteresis of typically 25°C. This data is based onstatisticalmeansandisnottestedduringtheregularmassproductionoftheIC. 7.4 Device Functional Modes The TPS6104x-Q1 operates with an input voltage range of 1.8 V to 6 V and can generate output voltages up to 28 V. The device operates in a pulse frequency modulation (PFM) scheme with constant peak current control. This control scheme maintains high efficiency over the entire load current range, and with a switching frequency upto1MHz,thedeviceenablestheuseofverysmallexternalcomponents. Theconvertermonitorstheoutputvoltage,andassoonasthefeedbackvoltagefallsbelowthereferencevoltage of typically 1.233 V, the internal switch turns on and the current ramps up. The switch turns off as soon as the inductor current reaches the internally set peak current of typically 400 mA (TPS61040-Q1) or 250 mA (TPS61041-Q1). See Peak Current Control for more information. The second criteria that turns off the switch is the maximum ON-time of 6 µs (typical). This is just to limit the maximum ON-time of the converter to cover for extreme conditions. As the switch is turned off, the external Schottky diode is forward biased delivering the current to the output. The switch remains off for a minimum of 400 ns (typical), or until the feedback voltage drops below the reference voltage again. Using this PFM peak-current control scheme, the converter operates in discontinuous conduction mode (DCM) where the switching frequency depends on the output current, which results in high efficiency over the entire load current range. This regulation scheme is inherently stable, allowing awiderselectionrangefortheinductorandoutputcapacitor. 10 SubmitDocumentationFeedback Copyright©2005–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS61040-Q1 TPS61041-Q1

Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The TPS6104x-Q1 is designed for output voltages up to 28 V with an input voltage range of 1.8 V to 6 V. TPS61040-Q1 can operate up to 400-mA typical peak load current and TPS61040-Q1 can operate up to 250-mA typical peak load current.

The selection of the inductor together with the nominal load current, input and output voltage of the application determines the switching frequency of the converter. Depending on the application, TI recommends inductor values from 2.2µH to 47 µH. The maximum inductor value is determined by the maximum ON-time of the switch, typically 6 µs. The peak current limit of 400 mA (typically) must be reached within this 6-µsperiodforproperoperation.

Therefore, select the inductor value that ensures the maximum switching frequency at the converter maximum load current is not exceeded. ThemaximumswitchingfrequencyiscalculatedusingEquation2.

The inductor value has less effect on the maximum available load current and is only of secondary order. The best way to calculate the maximum available load current under certain operating conditions is to estimate the expected converter efficiency at the maximum load current. This number can be taken out of the efficiency graphs shown in Figure 1, Figure 2, Figure 3, and Figure 4. The maximum load current can then be estimated usingEquation4. I 2 ´L ´ f P S(max) I = h load(max) 2´(V - V ) OUT IN Where: • I =PeakcurrentasdescribedinPeakCurrentControl P • L=Selectedinductorvalue • f =Maximumswitchingfrequencyascalculatedpreviously S(max) • η=Expectedconverterefficiency.Typically70%to85%. (4) The maximum load current of the converter is the current at the operation point where the converter starts to enter the continuous conduction mode. Usually the converter should always operate in discontinuous conduction mode. Last, the selected inductor must have a saturation current that exceeds the maximum peak current of the converter(ascalculatedinPeakCurrentControl).UsethemaximumvalueforI forthiscalculation. LIM Another important inductor parameter is the DC resistance. The lower the DC resistance, the higher the efficiency of the converter.

Smaller values can be used to reduce the noise sensitivity of thefeedbackpin. A feed-forward capacitor across the upper feedback resistor R1 is required to provide sufficient overdrive for the error comparator. Without a feed-forward capacitor, or one whose value is too small, the TPS6104x-Q1 shows double pulses or a pulse burst instead of single pulses at the switch node (SW), causing higher output voltage ripple.Ifthishigheroutputvoltagerippleisacceptable,thefeed-forwardcapacitorcanbeleftout. The lower the switching frequency of the converter, the larger the feed-forward capacitor value required. A good starting point is to use a 10-pF feed-forward capacitor. As a first estimation, the required value for the feed- forwardcapacitorattheoperationpointcanalsobecalculatedusingEquation6.

Therefore, when concern for line regulation is paramount, the selected feed-forward capacitor must be as small as possible. See the next sectionformoreinformationaboutlineandloadregulation. 8.2.2.3 LineandLoadRegulation The line regulation of the TPS6104x-Q1 depends on the voltage ripple on the feedback pin. Usually a 50-mV peak-to-peakvoltagerippleonthefeedbackpinFBgivesgoodresults. Some applications require a very tight line regulation and can only allow a small change in output voltage over a certain input voltage range. If no feed-forward capacitor C is used across the upper resistor of the voltage FF feedback divider, the device has the best line regulation. Without the feed-forward capacitor the output voltage rippleishigherbecausetheTPS6104x-Q1showsoutputvoltageburstsinsteadofsinglepulsesontheswitchpin (SW), increasing the output voltage ripple. Increasing the output capacitor value reduces the output voltage ripple. If a larger output capacitor value is not an option, a feed-forward capacitor C can be used as described in the FF previous section. The use of a feed-forward capacitor increases the amount of voltage ripple present on the feedback pin (FB). The greater the voltage ripple on the feedback pin (≥50 mV), the worse the line regulation. Therearetwowaystoimprovethelineregulationfurther: 1. Use a smaller inductor value to increase the switching frequency which will lower the output voltage ripple, aswellasthevoltagerippleonthefeedbackpin. 2. Add a small capacitor from the feedback pin (FB) to ground to reduce the voltage ripple on the feedback pin down to 50 mV again.

A 4.7-μF ceramic input capacitor is sufficient for most of the applications. For better input voltage filtering this value can be increased. See Table 4 andtheTypicalApplicationsectionforinputcapacitorrecommendations. 8.2.2.6 DiodeSelection To achieve high efficiency, a Schottky diode must be used. The current rating of the diode must meet the peak current rating of the converter as it is calculated in the section peak current control. Use the maximum value for I for this calculation. Table 5 lists the few typical Schottky Diodes for LCD Bias Supply design shown in LIM Figure 12.
