SD42524
1A High Power LED Driver with 636V 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
* 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
APPLICATIONS
* MR16 LED spotlight
* LED illuminance
* LED street lamp
