Texas Instruments TPS62170-Q1

Description

The TPS6217x-Q1 family is an easy to usesynchronous step down DC-DC converter 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 their wide operating input voltage range of 3 Vto 17 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 draw quiescentcurrent of about 17 μA 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 andshutdown current consumption is less than 2 μA.The device, available in adjustable and fixed outputvoltage versions, is packaged in an 8-pin WSONpackage measuring 2 × 2 mm (DSG).
