Texas Instruments TPS62172

Description

The TPS6217x device family are easy to usesynchronous step-down DC-DC converters optimizedfor applications with high power density. A highswitching frequency of typically 2.25 MHz allows theuse of small inductors and provides fast transientresponse as well as high output voltage accuracy byutilization of the DCS-Control™ topology.With its wide operating input voltage range of 3 V to17 V, the devices are ideally suited for systemspowered from either a Li-Ion or other battery as wellas from 12-V intermediate power rails. It supports upto 0.5-A continuous output current at output voltagesbetween 0.9 V and 6 V (with 100% duty cycle mode).Power sequencing is also possible by configuring theenable and open-drain power good pins.In power save mode, the devices show quiescentcurrent of about 17 μA from VIN. Power save mode,entered automatically and seamlessly if the load issmall, maintains high efficiency over the entire loadrange. In shutdown mode, the device is turned offand shutdown current consumption is less than 2 μA.
