TS19451 Datasheet (Taiwan Semiconductor)

TS19451, AC/DC WLED Driver

The TS19451 is a PWM high efficiency LED driver control IC.

It allows efficient operation of LED strings from voltage source ranging up to 400VDC.

It includes an internal high voltage switching MOSFET controlled with fixed off-time of approximately 10.5µS.

The LED string is driven at constant curren
