Highly-integrated CCM PFC Controller enables easy EnergyStar compliance, eliminates 54 external devices.

 Fairchild Semiconductor has leveraged its expertise in power to develop a CCM PFC controller for 300W to 2kW power supply designs that brings high system efficiency, high power factor and low THD. This highly-integrated controller simplifies EnergyStar-compliant designs and cuts BOM costs by eliminating the need for as many as 54 external components that would be required by other solutions.

Fairchild’s FAN6982 maintains high system efficiency at light load conditions to meet 20 percent load system efficiency requirements of ENERGY STAR regulations and Climate Savers Computing Initiatives. It achieves this by reducing capacitive switching losses and by reducing the voltage conversion ratio, which results in less conduction losses in the boost switch.

This CCM PFC controller reduces external components and offers ease of design through its high level of integration. Features of the CCM PFC controller are: built-in brown-out protection, eliminating 12 components; adjustable PFC output, eliminating 17 components; RDY pin for power-on-sequence, eliminating 15 components; 30V operating voltage capability, eliminating 10 components; and PFC soft-start, eliminating 4 components – in total decreasing bill of materials (BOM) by 54 devices.

Since many AC-sourced electronic applications have a microphone, amplifier or loudspeaker, which need an accurate reproduction of sound, this controller offers exceptionally low Total Harmonic Distortion (4.6 percent at full load) which reduces these harmonics and meets class D requirements of IEC 1000-3-2. The FAN6982 does this through its switching-charge technology that senses input current and voltage directly, helping to improve PF and THD.

Fairchild Semiconductor provides the industry’s most comprehensive portfolio of products for AC-DC power supplies. From CCM PFC controllers to BCM PFC controllers, these solutions help electronics to achieve higher levels of efficiency, lower standby power and ease of design. 

The FAN6982 CCM PFC controller is priced at US $0.69 in 1,000 quantity pieces. Samples of the FAN6982  are available now, with production-level quantities delivered in: 8 weeks ARO.
