      SD42530
      BUCK LED DRIVER WITH 8~80V INPUT

         The SD42530 is a buck LED driver with external power MOSFET, it can be used to drive one or more LEDs in series in BUCK mode. Its input voltage ranges from 8V to 80V, the output current is adjustable with good constant current accuracy. It provides built-in temperature protection, current limit protection, output short circuit protection, etc.

          The SD42530 adopts current mode control which provides fast transient response, excellent constant current characteristic and simple loop stabilization design. It has high efficiency: 96% for buck mode.
