PFS7527H

HiperPFS™-3 devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver, ultra-low reverse recovery (Qspeed™) diode and high-voltage power MOSFET in a single, low-profile (GROUND pin connected) power package. HiperPFS-3 devices eliminate the PFC converter’s need for external current sense resistors and the associated power loss and use an innovative control technique that adjusts the switching frequency over output load, input line voltage, and even input line cycle. HiperPFS-3’s innovative variable frequency continuous conduction mode operation (VF-CCM) minimizes switching losses by maintaining a low average switching frequency, while modulating the switching frequency in order to suppress EMI, the traditional challenge with continuous conduction mode solutions. Applications includes PC, high-power adaptors, printer, high-power LED lighting, LCD TV, industrial and appliance, video game consoles, generic PFC converters, 80 Plus™ platinum designs.
