SDH7520
POWER FACTOR CORRECTION (CRITICAL CONDUCTION MODE) CONTROLLER
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.
