TPS62172DSGR is easy to use synchronous step-down DC-DC converters 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 its wide operating input voltage range of 3 V to 17 V, the TPS62172DSGR is ideally suited for systems powered from either a Li-Ion or other battery as well as from 12-V intermediate power rails. TPS62172DSGR supports up to 0.5-A continuous output current at output voltages between 0.9 V and 6 V (with 100% duty cycle mode).

TPS62172DSGR——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 17 µA from VIN. Power save mode, entered automatically and seamlessly if the load is small, maintains high efficiency over the entire load range. In shutdown mode, the TPS62172DSGR is turned off and shutdown current consumption is less than 2 µA.

The TPS62172DSGR available in adjustable and fixed output voltage versions, is packaged in a 2-mm × 2-mm 8-pin WSON package (DSG).
