General Description

The TS19453 is a PWM high efficiency programmable current LED driver with PWM dimming 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 12µS.

The LED string is driven at constant current, thus providing constant light output and enhanced reliability. The

output current is internally programmable up to 50mA. The peak current control scheme provides good regulation

of the output current throughout the universal AC line voltage range of 85~264VAC or DC input voltage of

20~400V
