FAN6204A

mWSaver™ Synchronous Rectification Controller for

Flyback and Forward Freewheeling Rectification

Features

Description

mWSaver™ Technology:

FAN6204A

secondary-side

synchronous

rectification (SR) controller to drive SR MOSFET for

improving efficiency. The IC is suitable for flyback

converters and forward free-wheeling rectification.

Internal Green Mode to Stop SR Switching for

Lower No-Load Power Consumption

1.1 mA Ultra-Low Green Mode Operating

Current

FAN6204A can be applied in continuous or

discontinuous conduction mode (CCM and DCM) and

quasi-resonant (QR) flyback converters based on the

proprietary innovative linear-predict timing-control

technique. The benefits of this technique include a

simple control method without current-sense circuitry to

accomplish noise immunity.

SR Controller

Suited for Flyback Converter in QR, DCM, and

CCM Operation

Suited for Forward Freewheeling Rectification

PWM Frequency Tracking with Secondary-Side

Winding Voltage Detection

With PWM frequency tracking and secondary-side

winding voltage detection, FAN6204A can operate in

both fixed- and variable-frequency systems.

Ultra-Low V_DDOperating Voltage for Various Output

Voltage Applications (5 V~24 V)

In Green Mode, the SR controller stops all SR switching

operation to reduce the operating current. Power

consumption is maintained at minimum level in light-

load condition.

V_DDPin Over-Voltage Protection (OVP)

12 V (Typical) Gate Driver Clamp
