Beschreibung

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 22uA in normal mode and 4.8uA in Sleep Mode. In Sleep Mode, the efficiency at very low load currentscan be increased by as much as 20%. In shutdown mode, the shutdown current is less than 2uA 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.
