1A High Power LED Driver with 6～36V Input

DESCRIPTION

The SD42524 is a step-down PWM control LED driver with a built-in

power MOSFET. It achieves 1A continuous output current in 6~36V

input voltage range. It provides thermal shutdown circuit, current limit

circuit and PWM dimming circuit.

The SD42524 adopts current mode control which provides fast

transient response and simple loop stabilization design. It has high

efficiency up to more than 96%, and has excellent constant current

characteristic when the input/output voltage changed, with the

excellent current accuracy within ±1%

FEATURES

* 6-36V input voltage range

* Maximum 1A output current

* 0.40Ω built-in power MOSFET

* Integrate Jitter function

APPLICATIONS

* MR16 LED spotlight

* LED illuminance

* LED street lamp

* Thermal compensation

* PWM dimming function

* 280kHz fixed frequency

* Excellent constant current accuracy ±1%

* High efficiency up to 96%

* Thermal shutdown

* Cycle-by-cycle over current protection
