SDH7520 adopts high voltage power supply, and omits auxiliary winding by adopting MOS gate zero crossing detection technology.

It uses patented COMP-saving capacitor technology to achieve excellent power factor correction and constant voltage output with only a few peripheral components, which greatly reduces the system cost.

It provides various protections, such as output over voltage protection, CS cycle-by-cycle current limit and over temperature protection etc.
