    The SDH752XSN is a high performance, critical conduction mode   under high load and discontinuous conduction mode under light load ,power factor correction (PFC) controller .It has built-in MOSFETs of different models.SDH752XSN 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, output under voltage protection, CS cycle-by-cycle current limit and over temperature protection etc.
