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.


Main feature

  • Single winding inductor booster system with reduced periphery

  • High voltage start-up and power supply

  • Gate Zero-crossing detection and critical conduction mode 

  • Fixed on time control

  • Patented closed-loop control technology, without peripheral compensation network, anti-moisture and anti-leakage

  • VCC under-voltage lockout

  • Output overvoltage protection

  • CS cycle-by-cycle current limit

  • Over temperature protection
