Fairchild Intros New FAN4822 PFC Controller

Fairchild Semiconductor International (San Jose, CA) introduced the new FAN4822 PFC controller, targeted for power supplies of 500W or more. The FAN4822 is an average-current boost-type device employing zero-voltage switching control circuitry designed for efficient operation at high switching frequencies. It is suitable for high-power applications such as servers, routers, power supplies and telecom switching equipment.

The continuous boost architecture allows designs to achieve the high power factor (up to 98 percent) and the low total harmonic distortion necessary to comply with “green” initiatives, such as the IEC 1000-3-2 standard for energy efficiency and noise reduction in consumer electronics. The built-in circuitry allows designers to use smaller, lower cost components to save board space while reducing switching losses and noise caused by electromagnetic interference.

Safety features on the FAN4822 include under-voltage lockout, over-voltage

protection, peak-current limiting and input-voltage brownout protection. The FAN4822 is rated for operation over the -40 to +85 degrees C temperature range, and is available in 14-lead plastic DIP and wide-body 16-lead SOIC packages.

Available now, the 14-lead PDIP (FAN4822IN) and the 16-lead SOIC (FAN4822IM) is priced at $3.21 for 1,000 pieces. Delivery is 8 to 10 weeks ARO.
