The TPS6215x family is an easy-to-use synchronous step down dc-dc converter optimized forapplications with high power density. A high switching frequency of typically 2.5 MHz allows theuse of small inductors and provides fast transient response as well as high output-voltage accuracyby the use of DCS-Control topology.

With their wide operating input-voltage range of 3 V to 17 V, the devices are ideallysuited for systems powered from either Li-Ion or other batteries as well as from 12-V intermediatepower rails. The devices support up to 1-A continuous output current at output voltages between 0.9V and 6 V (in 100% duty-cycle mode). The soft-start pin controls the output-voltage start-up ramp,which allows operation as either a standalone power supply or in tracking configurations. Powersequencing is also possible by configuring the enable (EN) and open-drain power-good (PG)pins.

In power-save mode, the devices draw quiescent current of about 17 µA from VIN.Power-save-mode, entered automatically and seamlessly if the load is small, maintains highefficiency over the entire load range. In shutdown mode, the device turns off and currentconsumption is less than 2 µA.

The device, available in adjustable- and fixed-output-voltage versions, comes in a16-pin VQFN package measuring 3 × 3 mm (RGT).
