The SDH7520 is a high performance, critical conduction mode power factor correction (PFC) controller.
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.
