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
Features
● Adjust constant output current up to 50mA(typ)
● Universal 85~264VAC operation
● Over temperature protection with hysteresis
● PWM dimming
● Fixed off-time buck converter
● Internal 475V power MOSFET
Typical Application Circuit
Application
● Decorating LED lighting
● LED lamps with AC or DC operation.
