1.2 Description

The TPS65735 is a PMU for active shutter 3D glasses consisting of an integrated power path, linear

charger, LDO, boost converter, and full H-bridge analog switches for left and right shutter operation in a

pair of active shutter 3D glasses. In addition to the power devices, a typical 3D glasses system contains

both a microcontroller and a communications front end (IR, RF, or other) in order to handle the

communication and synchronous operation along with a 3D television.
