Description

• Parameters: POWER FACTOR CORRECTION CONTROLLER
• Description: The SDH7520SN is a high performance power factor correction (PFC) controller. The circuit operates in Critical conduction mode (BCM) under high load values. For light loads, it will operate in DCM. SDH7520SN adopts high voltage power supply, and removes 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 gre
• Features: 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 Light load frequency reduction control Patented closed-loop control technology, without peripheral compensation network, anti-moisture and anti-leakage VCC under-voltage lockout Output overvoltage protection and output under voltage protection CS cycle-by-cycle current limit Over temperature protection
• Applications: Power Supply
