3 Description

The TPS92410 is an advanced linear driver with high

voltage start-up intended for use in low power, offline

LED lighting applications. It can be used to regulate

the average LED current through LEDs in conjunction

with the TPS92411 direct drive switch.

The TPS92410 features a reference voltage that can

be used to set the current level as well as the thermal

foldback threshold. A multiplier is included to obtain

excellent power factor while maintaining good line regulation. Other features include under-voltage

lockout, over-voltage protection, forward phase

dimmer detection with change to constant current

mode, thermal foldback, and thermal shutdown.
