PFS7628H, Power Factor Correction - PFC PFC CTRL 600V High PF 350W 385W

Semiconductors\Power Management ICs\Power Factor Correction - PFCHiperPFS™-4 PFC ControllersPower Integrations HiperPFS-4 PFC (Power Factor Correction) Controllers incorporate a Continuous Conduction Mode (CCM) boost PFC controller, gate driver and 600V power MOSFET in a single, low-profile (GROUND pin connected) power package. HiperPFS-4 devices eliminate need for external current sense resistors and their associated power loss, and use an innovative control technique that adjusts the switching frequency over output load, input line voltage, and input line cycle. This control technique maximizes efficiency over the entire load range, particularly at light loads. Additionally, it minimizes the EMI filtering requirements due to its wide bandwidth spread spectrum effect.
