TPS22933 Overview
The TPS22933 device is a small, low rON, triple-input power multiplexer with auto-input selection and a lowdropout linear regulator. The device contains three Pchannel MOSFETs that can operate over an input voltage range of 2.5 V to 12 V. The TPS22933 automatically selects the highest level (from BAT, USB, and DC_IN) and enables that input to source the LDO.
