SG6932 - PFC / Forward PWM Controller

Description

The highly integrated SG6932 is designed for power supplies with boost PFC and forward PWM.

It requires very few external components to achieve versatile protections and compensation.

It is available in 16-pin DIP and SOP packages.

Features

  • Interleaved PFC/PWM Switching Low Operating Current Innovative Switching-Charge Multiplier-divider Multi-vector Control for Improved PFC Output Transient Response Average Current Mode for Input-current Shaping PFC Over-voltage and Under-voltage Protections PFC and PWM Feedback Open-loop Protection Cycle-by-cycle Current Limiting for PFC/PWM Slope Compensation for PWM Selectable PWM Maximum Duty Cycle: 50%, 65% Brownout Prote.
