During PWM operation, the converter uses a unique fast response, voltage mode, controller scheme with input voltage feed forward. This achieves good line and load regulation and allows the use of small ceramic input and output capacitors. At the beginning of each clock cycle initiated by the clock signal (S), the P-channel MOSFET switchisturnedon,andtheinductorcurrentrampsupuntilthecomparatortripsandthecontrol logic turns off the switch. The current limit comparator also turns off the switch in case the current limit of the P-channel switch is exceeded. Then, the N-channel rectifier switch is turned on and the inductor current ramps down. The next cycle isinitiatedbytheclocksignal,againturningofftheN-channelrectifierandturningontheP-channelswitch. The GM amplifier and input voltage determines the rise time of the sawtooth generator; therefore, any change in input voltage or output voltage directly controls the duty cycle of the converter. This gives a very good line and loadtransientregulation. POWER-SAVE MODE OPERATION As the load current decreases, the converter enters the power-save mode operation. During power-save mode, the converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current to maintain high efficiency. Two conditions allow the converter to enter the power-save mode operation. One is when the converter detects discontinuous conduction mode. The other is when the peak switch current in the P-channelswitchgoesbelowtheskipcurrentlimit.Thetypicalskipcurrentlimitcanbecalculatedas: I (cid:2)66mA(cid:1) Vin skip 160(cid:1) During the power-save mode, the output voltage is monitored with the comparator (comp) by the thresholds comp low and comp high. As the output voltage falls below the comp low threshold set to 0.8% typical above Vout, the P-channel switch turns on. The P-channel switch is turned off as the peak switch current is reached. Thetypicalpeakswitchcurrentcanbecalculated: I (cid:2)66mA(cid:1) Vin peak 80(cid:1) The N-channel rectifier is turned on and the inductor current ramps down. As the inductor current approaches zero, the N-channel rectifier is turned off and the P-channel switch is turned on again, starting the next pulse. Theconvertercontinuesthesepulsesuntilthecomphighthreshold(settotypically 1.6% above Vout) is reached. The converter enters a sleep mode, reducing the quiescent current to a minimum. The converter wakes up again as the output voltage falls below the comp low threshold. This control method reduces the quiescent current typically to 15 m A and reduces the switching frequency to a minimum, thereby achieving high converter efficiency at light load. Setting the skip current thresholds to typically 0.8% and 1.6% above the nominal output voltage at light load current results in a dynamic output voltage achieving lower absolute voltage drops during heavy load transientchanges.Thisallowstheconvertertooperatewithasmalloutputcapacitorofjust10m Fandstill have a low absolute voltage drop during heavy load transient changes. See Figure 14 for detailed operation of the power-savemode. 10 SubmitDocumentationFeedback Copyright©2003–2009,TexasInstrumentsIncorporated ProductFolderLink(s):TPS62220TPS62221 TPS62222 TPS62223 TPS62224 TPS62225TPS62227 TPS62228 TPS62229

DYNAMIC VOLTAGE POSITIONING As described in the power-save mode operation sections and as detailed in Figure 14, the output voltage is typically 0.8% above the nominal output voltage at light load currents, as the device is in power-save mode. This gives additional headroom for the voltage drop during a load transient from light load to full load. During a load transientfromfullloadtolightload,thevoltageovershootisalsominimized due to active regulation by turning on theN-channelrectifierswitch. DIGITAL SELF-CALIBRATION In addition to the control circuit as shown in the block diagram, the TPS6222x series uses an internal digital self-calibration of the output voltage to minimize DC load and line regulation. This method of self-calibration allows simple internal loop compensation without the use of external components. The device monitors the output voltage and as soon as the output voltage drops below typically 1.6% or exceeds typically 1.6% of Vout the duty cycle will be adjusted in digital steps. As a result, the output voltage changes in digital steps either up or down where one step is typically 1% of Vout. This results in virtually zero line and load regulation and keeps the outputvoltagetolerancewithin±3%overloadandlinevariations. SOFT START The TPS6222x has an internal soft-start circuit that limits the inrush current during start-up. This prevents possible voltage drops of the input voltage in case a battery or a high impedance power source is connected to the input of the TPS6222x. The soft start is implemented as a digital circuit increasing the switch current in steps of typically 83 mA, 167 mA, 335 mA and then the typical switch current limit of 670 mA. Therefore, the start-up timemainlydependsontheoutputcapacitorandloadcurrent.

SLVS491E–SEPTEMBER2003–REVISEDFEBRUARY2009 APPLICATION INFORMATION OUTPUT FILTER DESIGN (INDUCTOR AND OUTPUT CAPACITOR) The TPS6222x series of step-down converter has internal loop compensation. Therefore, the external L-C filter has to be selected to work with the internal compensation. This is especially important for the fixed output voltage version. The adjustable output voltage version allows external capacitors across the feedback divider resistors. This allows higher flexibility of the output filter selection when using the adjustable output voltage deviceTPS62220. FixedOutputVoltageVersion The internal compensation is optimized to operate with an output filter of L = 10 m H and C = 10 m F. Such an O outputfilterhasitscornerfrequencyat: ƒc(cid:2) 1 (cid:2) 1 (cid:2)15.9kHz 2(cid:2)(cid:1)(cid:3)L(cid:1)CO 2(cid:2)(cid:1)(cid:3)10(cid:1)H(cid:1)10(cid:1)F with L = 10 m H, C = 10 m F O Asageneralruleofthumb,theproductL×Cshouldnotmoveoverawiderangewhenselectingadifferent output filter. This is because the internal compensation is designed to work with a certain output filter corner frequency as calculated above. This is especially important when selecting smaller inductor or capacitor values that move the corner frequency to higher frequencies. However, when selecting the output filter a low limit for the inductor value exists due to other internal circuit limitations. For the TPS6222x series the minimum inductor value should be kept at 4.7m H. Selecting a larger output capacitor value is less critical because the corner frequency moves to lowerfrequenciescausingfewerstabilityproblems.ThepossibleoutputfiltercombinationsarelistedinTable1: Table1.OutputFilterCombinationsforFixedOutputVoltageVersions V L C O O ≤2V 4.7m H ≥22m F(ceramiccapacitor) ≤2V 6.8m H ≥22m F(ceramiccapacitor) ≤2V 10m H ≥10m F(ceramiccapacitor) >2V 10m H 10m F(ceramiccapacitor) AdjustableOutputVoltageVersion When the adjustable output voltage version TPS62220 is used, the output voltage is set by the external resistor divider.SeeFigure15.

To keep the operating quiescent current to a minimum, the feedback resistor divider should have high impedance with R1 + R2 ≤ 1 MΩ. In general, for the adjustable output voltage version, the same stability considerations are valid as for the fixed output voltage version. Because the adjustable output voltage version uses an external feedback divider, it is possible to adjust the loop gainusingexternalcapacitorsacrossthefeedbackresistors.Thisallowsawiderselectionofpossible output filter components.

Especially at high-switching frequencies the core material has a higher impact on efficiency. When using small chip inductors, the efficiency is reduced mainly due to higher inductor core losses. This needs to be considered when selecting the appropriate inductor. The inductor value determines the inductor ripple current. The larger the inductor value, the smaller the inductor ripple current and the lower the conduction losses of the converter. Conversely, larger inductor values cause a slower load transient response. To avoid saturation of the inductor, the inductor should be rated at least for the maximum output current of the converter plus the inductor ripple current that is calculatedas: V O 1 - V DI I L DI = V x I max = I max + L O L x f L O 2 where: • f=switchingfrequency(1.25-MHztypical,800-kHzminimal) • L=inductorvalue • ΔI =peak-to-peakinductorripplecurrent L • I =maximuminductorcurrent L,max The highest inductor current occurs at maximum Vin. A more conservative approach is to select the inductor currentratingjustforthemaximumswitchcurrentof880mA.SeeTable3forinductorselection. 14 SubmitDocumentationFeedback Copyright©2003–2009,TexasInstrumentsIncorporated ProductFolderLink(s):TPS62220TPS62221 TPS62222 TPS62223 TPS62224 TPS62225TPS62227 TPS62228 TPS62229

Also, the input capacitor must be sufficiently large to stabilize the input voltage during heavy load transients. For good input voltage filtering, usually a 4.7 m F input capacitor is sufficient. It can be increased without any limit for better input-voltage filtering. Ceramic capacitors show better performance because of the low ESR value, and they are less sensitive against voltage transients and spikes compared to tantalum capacitors. Place the input capacitor as close as possible to the input and GND pin of the device for best performance (see Table 4 for capacitorselection). OUTPUT CAPACITOR SELECTION The advanced fast response voltage mode control scheme of the TPS6222x allows the use of tiny ceramic capacitors with a minimum value of 10 m F without having large output voltage under and overshoots during heavy load transients. Ceramic capacitors with low ESR values have the lowest output voltage ripple and are recommended. If required, tantalum capacitors may be used as well (see Table 4 for capacitor selection). At nominal load current, the device operates in power-save mode, and the output voltage ripple is independent of the output capacitor value. The output voltage ripple is set by the internal comparator thresholds. The typical outputvoltagerippleis1%oftheoutputvoltageV .

If the layout is not carefully done, the regulator shows stability problems as well as EMI problems. Therefore, use wide and short traces for the main current paths, as indicated in bold in Figure 16. The input capacitor, as well as the inductor and output capacitor, should be placed as close as possible to the IC pins. In particular, the input capacitor needs to be placed as close as possible to the IC pins, directly across the Vin and GND pin. The feedback resistor network must be routed away from the inductor and switch node to minimize noise and magnetic interference. To further minimize noise from coupling into the feedback network and feedback pin, the ground plane or ground traces must be used for shielding. This becomes important especiallyathighswitchingfrequenciesof1.25MHz.
