Three-channel interleaved CCM PFC controller creates compact designs
Allowing designers to use small passive components in high power applications, such as air conditioner power supplies, Fairchild claims that its FAN9673, interleaved continuous conduction mode (CCM) PFC controller is an industry first. It enables high power PFC control using the smallest possible inductors and lowest possible power rating switching devices, extending the capacitors' lifetime, says the company. Unlike other solutions that provide two or less channel capabilities it can switch between one-, two- or three-channels with good phase management. The device also features a simple differential current sensing resistor and configurable output voltage control, enabling an easy, compact, cost-effective design for high power PFC applications up to 9kW. It can be used in high power AC/DC power supplies and DC motor supplies as well as white goods, server and telecoms power supplies, UPS and industrial welding supplies.
