Description

The TPS6216X family is an easy to use synchronous step down DC-DC converter optimized for applications with high power density. A high switching frequency of typically 2.25MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by utilization of the DCS-Control topology.

With its wide operating input voltage range of 3V to 17V, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12V intermediate power rails. It supports up to 1A continuous output current at output voltages between 0.9V and 6V (with 100% duty cycle mode).

Power sequencing is also possible by configuring the Enable and open-drain Power Good pins.

In Power Save Mode, the devices show quiescent current of about 17µA from VIN. Power Save Mode, entered automatically and seamlessly if load is small, maintains high efficiency over the entire load range. In Shutdown Mode, the device is turned off and shutdown current consumption is less than 2µA.

The devices, available in adjustable and fixed output voltage versions, are packaged in an 8-pin WSON package measuring 2 × 2 mm (DSG) or 8-pin MSOP package (DGK).
