Compact AC-DC converter PFM™

Overview
The PFM4914VB6M48D0CA0 belongs to the PFM™ family of isolated AC-DC converters with integrated Active Power Factor Correction (PFC). It uses a low-profile 4914 VIA package for chassis or PCB mounting and delivers 400 W across the full input range (85–264 VAC). Typical PFC performance is >0.95 depending on filter and load. Minimal external components are required for fast wall-plug-to-POL designs when combined with Vicor POL buck and buck-boost regulators.
