TPS92410 Linear Controller for Offline LED Drivers

Texas Instruments' 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 undervoltage lockout, overvoltage protection, forward phase dimmer detection with change to constant current mode, thermal foldback, and thermal shutdown.
