SD42560 Overview
The SD42560 is PWM control LED driver in Buck/Boost/Buck-Boost modes with thermal shutdown circuit, current limit circuit and PWM dimming circuit. And good line regulation and load regulation are available with wide voltage input. The SD42560 adopts current mode control which provides fast transient response, excellent constant current characteristic and simple loop stabilization design.
