The TPS6217x-Q1 family is an easy to use synchronous step-down DC-DC converter optimizedfor applications with high power density. A high switching frequency of typically 2.25 MHz allowsthe use of small inductors and provides fast transient response as well as high output voltageaccuracy by utilization of 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 0.5-A continuous output current at output voltages between 0.9 V and6 V (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 device, available in adjustable and fixed output voltage versions, is packaged in an8-pin WSON package measuring 2 × 2 mm (DSG).
