onsemi Power Factor Controller Evaluation Board Buck-Boost Converter for NCP1654BD65R2G for Power Factor Controller

The NCP1654GEVB is a Power Factor Controller to efficiently drive Continuous Conduction Mode (CCM) step-up pre-converters. The NCP1654 allows operation in Follower Boost mode to drastically lower the pre-converter size and cost, in a straight-forward manner. The NCP1654 is a continuous conduction mode and fixed frequency controller (65kHz). The coil (650 uH) is selected to limit the peak to peak current ripple in the range of 36 % at the sinusoid top, in full load and low line conditions.
