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...
