Fairchild Semiconductor’s Synchronous Rectification Controller Compatible to Flyback & Forward Topologies; Multiple Operati...

In order to meet increased power efficiency demands and regulatory standards for desktop PCs, All-in-One (AIO) PCs and notebook adaptors, designers need secondary-side synchronous rectification (SR) controllers that can increase power efficiency while integrating more functions.

Fairchild Semiconductor (NYSE: FCS), a leading global supplier of high performance power and mobile products, developed the FAN6204 to do just that.

Using a proprietary, innovative linear prediction timing-control technique, not limited to the RDS(ON) of the SR MOSFET, the FAN6204 is suitable for fixed frequency or quasi-resonant (QR) flyback converters and discontinuous or continuous conduction mode (DCM and CCM) operation. This technique includes a simple control method without current-sense circuitry, which provides better noise immunity.

With PWM frequency tracking and secondary-side winding voltage detection, the device can operate in both fixed- and variable-frequency systems, making it adaptable to flyback and forward free-wheeling topologies.

The FAN6204 also features an ultra-low green mode operating current (1.1mA typical). This internal green mode provides lower no-load power consumption and higher light-load efficiency. In green mode, the SR MOSFET stops switching and the controller stops major internal IC block operations to further reduce the operating current. In light-load conditions, power consumption is maintained at minimum levels.

The FAN6204 is ideal for adapters and chargers, AIO computers, LCD TVs and monitors, LED street lights, notebook adapters (Slim Pack), as well as DVD players and set-top boxes.

Other features of the FAN6204 include an ultra-low VDD operating voltage (5V-28.5V), VDD pin over-voltage protection (OVP) and a 12V (typical) gate drive clamp. The device is available in an 8-pin SOP package.

Fairchild Semiconductor enables engineers to drive innovation in their designs by offering smaller size and increased performance through advanced silicon and package options. The FAN6204 is part of a broad portfolio of devices designed to address the designer’s power needs. Fairchild Semiconductor: The Right Technology for Your Success™
