The TPS6216x-Q1 are easy to use synchronous step down DC-DC converters optimized forapplications with high power density. A high switching frequency of typically 2.25 MHz allows theuse of small inductors and provides fast transient response as well as high output voltage accuracyby using the 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 a Li-Ion or other battery as well as from 12-V intermediatepower rails. It supports up to 1-A continuous output current at output voltages between 0.9 V and 6V (with 100% duty cycle mode).
Power sequencing is also possible by configuring the Enable and open-drain Power Goodpins.
In Power Save Mode, the devices draw quiescent current of about 17 µA from VIN. PowerSave Mode, entered automatically and seamlessly if load is small, maintains high efficiency overthe entire load range. In Shutdown Mode, the device is turned off and shutdown current consumptionis less than 2 µA.
The devices are available in adjustable and fixed output voltage versions and arepackaged in an 8-pin WSON package measuring 2 × 2 mm (DSG).
