PFC/PWM controller provides high efficiency, consumes less than 300 mW

PFC/PWM controller provides high efficiency, consumes less than 300 mW

The FAN6920MR integrated critical-mode PFC and quasi-resonant current-mode PWM controller meets regulatory requirements by providing >90% efficiency and

The device has a total harmonic distortion optimizer that reduces input current distortion at zero-crossing duration to improve THD performance. Additionally, it provides many protection functions including brownout, secondary-side open-loop and overcurrent with auto recovery, external auto-recovery protection triggering, and internal over-temperature shutdown. Available in a 16-pin SOP, the controller suits all-in-one computers, ac/dc netbook adapters, open-frame SMPS, battery chargers, LCD TV, and LED street lights. ($0.82 ea/1,000 — available now.)
