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.
