The SD42527 is a step-down PWM control LED driver with a built-in power MOSFET. It achieves 1A continuous output current in 6~60V input voltage range. It provides thermal shutdown circuit, current limit circuit and PWM dimming circuit.
The SD42527 adopts current mode control which provides fast transient response, excellent constant current characteristic and simple loop stabilization design. It has high efficiency up to 96%, and has excellent constant current characteristic. When the input/output voltage changed, the output current change rate is within ±1.5%.
