Description
General part information
TPS62171-Q1 Series
The TPS6217x-Q1 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 2.25 MHz 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 their wide operating input voltage range of 3 V to 17 V, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12-V intermediate power rails. It supports up to 0.5-A continuous output current at output voltages between 0.9 V and 6 V (with 100% duty cycle mode).
Power sequencing is also possible by configuring the Enable and open-drain Power Good pins.
