AC/DC WLED Driver with Internal MOSFET

Universal Switch Mode

SOT-89

Pin Definition:

1. Drain

2. GND

3. VDD

General Description

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 current, thus providing constant light output and enhanced reliability. The

output current is internally fixed at 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
