The controller topology supports forced PWM mode as well as power-save mode operation. Power-save mode operation reduces the quiescent current consumption down to 22 μA and ensures high conversion efficiency at light loads by skipping switch pulses. In forced PWM mode, the device operates on a quasi-fixed frequency, avoidspulseskipping,andallowsfilteringoftheswitchnoisebyexternalfiltercomponents. The TPS6223x devices offer fixed output voltage options featuring smallest solution size by using only three externalcomponents. The internal switch current limit of typical 850 mA supports output currents of up to 500 mA, depending on the operatingcondition. A significant advantage of TPS6223x compared to other hysteretic PWM controller topologies is its excellent DC and AC load regulation capability in combination with low-output voltage ripple over the entire load range which makesthispartwellsuitedforaudioandRFapplications. Once the output voltage falls below the threshold of the error comparator, a switch pulse is initiated, and the high-side switch is turned on. It remains turned on until a minimum ON-time of t expires and the output ONmin voltage trips the threshold of the error comparator or the inductor current reaches the high-side switch current limit. Once the high-side switch turns off, the low-side switch rectifier is turned on and the inductor current ramps downuntilthehigh-sideswitchturnsonagainortheinductorcurrentreacheszero.

It prevents the converter from turning on the switch or rectifier MOSFET under undefined conditions. The TPS6223x devices have a UVLO threshold set to 1.8 V (typical). Fully functional operation is permitted for input voltage down to the falling UVLO threshold level. The converter starts operation again once the input voltage trips the rising UVLO thresholdlevel. 8.3.2 EnableandShutdown The device starts operation when EN is set high and starts up with the soft-start as previously described. For proper operation, the EN pin must be terminated and must not be left floating, except for the TPS622319, which hasanintegrated1MΩalwaysactivepull-downresistor. Pulling the EN pin low forces the device into shutdown, with a shutdown quiescent current of typically 0.1 μA. In this mode, the P- and N-channel MOSFETs are turned off, the internal resistor feedback divider is disconnected, andtheentireinternal-controlcircuitryisswitchedoff. The EN input can be used to control power sequencing in a system with various DC – DC converters. The EN pin can be connected to the output of another converter, to drive the EN pin high and getting a sequencing of supplyrails. 8.3.3 ThermalShutdown As soon as the junction temperature, T , exceeds 150°C (typical) the device goes into thermal shutdown. In this J mode, the high-side and low-side MOSFETs are turned off. The device continues its operation when the junction temperaturefallsbelowthethermalshutdownhysteresis. 10 SubmitDocumentationFeedback Copyright©2009–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS62230TPS62231 TPS62232 TPS62233 TPS62234 TPS62235 TPS62236 TPS62237 TPS62238 TPS62239 TPS622310 TPS622311 TPS622312TPS622313 TPS622314 TPS622315 TPS622316 TPS622317 TPS622318 TPS622319

This limits input voltage drops when a battery or a high-impedance power source isconnectedtotheinputoftheconverter. The soft-start system generates a monotonic ramp up of the output voltage and reaches the nominal output voltagetypically100μsafterENpinwaspulledhigh. If the output voltage does not reached its target value by this time, such as in the case of heavy load, the converterthenoperatesinacurrentlimitmodesetbyitsswitchcurrentlimits. TPS6223x is able to start into a prebiased output capacitor. The converter starts with the applied bias voltage andrampstheoutputvoltagetoitsnominalvalue. 8.4.2 Power-SaveMode Connecting the MODE pin to GND enables the automatic PWM and power-save mode operation. The converter operates in quasi-fixed frequency PWM mode at moderate to heavy loads and in the pulse frequency modulation (PFM)modeduringlightloads,whichmaintainshighefficiencyoverawideloadcurrentrange.InPFMmode,the device starts to skip switch pulses and generates only single pulses with an ON-time of t . The PFM mode ONmin frequency depends on the load current and the external inductor and output capacitor values. The PFM mode of TPS6223x is optimized for low-output voltage ripple if small external components are used. Even at low output currents, the PFM frequency is above the audible noise spectrum and makes this operation mode suitable for audioapplications. TheON-timet canbeestimatedto: ONmin V t = OUT ´ 260ns ONmin V IN (1) Therefore,thepeakinductorcurrentinPFMmodeisapproximately: (V - V ) I = IN OUT ´ t LPFMpeak ONmin L (2) ThetransitionfromPFMintoPWMmodeandviceversacanbeestimatedto: I = 0.5 x I OUT_PFM/PWM LPFMpeak where • t :High-sideswitchON-time[ns] ON • V :Inputvoltage[V] IN • V :Outputvoltage[V] OUT • L:Inductance[μH] • I :PFMinductorpeakcurrent[mA] LPFMpeak • I :OutputcurrentforPFMtoPWMmodetransitionandviceversa[mA] (3) OUT_PFM/PWM 8.4.3 ForcedPWMMode Pulling the MODE pin high forces the converter to operate in a continuous conduction PWM mode even at light load currents. The advantage is that the converter operates with a quasi-fixed frequency that allows simple filtering of the switching frequency for noise-sensitive applications. In this mode, the efficiency is lower compared to the power save mode during light loads. This pin must be terminated except for the TPS622319 , which has anintegrated1MΩ alwaysactivepull-downresistor. For additional flexibility, it is possible to switch from power-save mode to forced PWM mode during operation. This allows efficient power management by adjusting the operation of the converter to the specific system requirements.

The current in the switches is monitored by current limit comparators. When the current in the P-channel MOSFET reaches its current limit, the P-channel MOSFET is turned off and the N-channel MOSFET is turned on to ramp down the current in the inductor. The high-side MOSFET switch can only turn on again, once the current in the low side MOSFET switch has decreased below the threshold of its current limit comparator. 12 SubmitDocumentationFeedback Copyright©2009–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS62230TPS62231 TPS62232 TPS62233 TPS62234 TPS62235 TPS62236 TPS62237 TPS62238 TPS62239 TPS622310 TPS622311 TPS622312TPS622313 TPS622314 TPS622315 TPS622316 TPS622317 TPS622318 TPS622319

The selected inductor has to be rated for its DC resistance and saturation current. The inductor ripple current (ΔI ) decreases with higher inductance and increases with higher V or V . Equation 5 L IN OUT calculates the maximum inductor current under static load conditions. The saturation current of the inductor must be rated higher than the maximum inductor current as calculated with Equation 6. This is recommended because duringheavyloadtransienttheinductorcurrentwillriseabovethecalculatedvalue.

To achieve high-efficiency operation, take care in selecting inductors featuring a quality factor above 25 at the switching frequency. Increasing the inductor value produces lower RMS currents, but degrades transient response. For a given physical inductor size, increasedinductanceusuallyresultsinaninductorwithlowersaturationcurrent.

Y5V and Z5U dielectric capacitors, aside from their wide variationincapacitanceovertemperature,becomeresistiveathighfrequencies. At light load currents, the converter operate in power save mode and the output voltage ripple is dependent on the output capacitor value and the PFM peak inductor current.

For most applications a 2.2-μF to 4.7-μF ceramic capacitor is recommended. The input capacitor can be increased without any limit for better input voltage filtering.

As a next step in the evaluation of the regulation loop, the load transient response is tested. The time between the application of the load transient and the turn on of the P-channel MOSFET, the output capacitor must supply all of the current required by the load. V immediately shifts by an amount equal to ΔI x ESR, where ESR OUT (LOAD) is the effective series resistance of C . ΔI begins to charge or discharge C generating a feedback error OUT (LOAD) O signal used by the regulator to return V to its steady-state value.

The output current of the input power supply must to be rated according to the supply voltage, output voltage and output current of the TPS6223x. 11 Layout 11.1 Layout Guidelines As for all switching power supplies, the layout is an important step in the design. Proper function of the device demands careful attention to PCB layout. Take care in the board layout to get the specified performance. If the layout is not carefully done, the regulator could show poor line and/or load regulation, stability issues, as well as EMI problems. It is critical to provide a low-inductance, impedance ground path. Therefore, use wide and short traces for the main current paths. The input capacitor must be placed as close as possible to the IC pins as well astheinductorandoutputcapacitor. Use a common power GND node and a different node for the signal GND to minimize the effects of ground noise.KeepthecommonpathtotheGNDpin,whichreturnsthesmallsignalcomponentsandthehighcurrentof the output capacitors as short as possible to avoid ground noise. The FB line must be connected to the output capacitorandroutedawayfromnoisycomponentsandtraces(forexample,SWline). 11.2 Layout Example Total area L1 is less than 12mm² V IN C 1 C2 GND V OUT Figure55.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
