Description

The TPS65735 device is a power management unit (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.
