TS19452 Datasheet (Taiwan Semiconductor)

TS19452, AC/DC WLED Driver

The TS19452 is a PWM high efficiency LED driver control IC.

It allows efficient operation of LED strings from voltage source ranging up to 450VDC.

It includes an internal high voltage switching MOSFET controlled with fixed off-time of approximately 12µS.

The LED string is driven at constant current,
