描述：The SD42522/22EH 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 SD42522/22EH adopts current mode control which provides fast transient response, excellent constant current characteristic and simple loop stabilization design. It has high efficiency up to more than 96%, the excellent current accuracy is within ±1% when input/output voltage change.
