Datasheet Summary
1A High Power LED Driver with 6～36V Input
DESCRIPTION
The SD42522 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. The SD42522 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%
