28V, 0.5A Step-Down Converter with SNOOZE Mode - TPS62175

TPS62175 (ACTIVE)

28V, 0.5A Step-Down Converter with SNOOZE Mode

Description

The TPS62175/7 is a high efficiency synchronous step-down DC-DC converter, based on the DCS-Control topology.

With a wide operating input voltage range of 4.75 to 28V, the device is ideally suited for systems powered from multi cell Li-Ion as well as 12V and even higher intermediate supply rails, providing up to 500mA output current.

The TPS62175/7 automatically enters Power Save Mode at light loads, to maintain high efficiency across the whole load range. As well, it features a Sleep Mode to supply applications with advanced power save modes like ultra low power micro controllers. The Power Good output may be used for power sequencing and/or Power On Reset.

The device features a typical quiescent current of 22µA in normal mode and 4.8uA in Sleep Mode. In Sleep Mode, the efficiency at very low load currents can be increased by as much as 20%. In shutdown mode, the shutdown current is less than 2µA and the output is actively discharged.

The TPS62175/7, available in an adjustable and a fixed output voltage version, is packaged in a small 2x3mm 10-pin WSON package.
