Description

General part information

TPS81256 Series

The TPS81256 device is a complete MicroSiP DC/DC step-up power solution intended for battery-powered portable applications. Included in the package are the switching regulator, inductor and input/output capacitors. Only a tiny additional output capacitor is required to finish the design.

The TPS81256 is based on a high-frequency synchronous step-up DC/DC converter optimized for battery-powered portable applications.

The DC/DC converter operates at a regulated 4-MHz switching frequency and enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
