NCP1654 - Power Factor Controller for Compact and Robust ...
DATA Semiconductor Components Industries, LLC, 2016 August, 2021 Rev. 71 Publication Order Number: NCP1654 /DPower Factor Controller forCompact and Robust ,Continuous ConductionMode Pre-ConvertersNCP1654 The NCP1654 is a Controller for Continuous Conduction Mode(CCM) Power Factor Correction step up pre converters. It controlsthe Power switch conduction time (PWM) in a fixed frequency modeand in dependence on the instantaneous coil in a SO8 package, the circuit minimizes the number ofexternal components and drastically simplifies the PFCimplementation.

When VFB goes above 105% VREF, OVP is activated and the Drive Output is disabled. When VFB goes below 8% VREF, the device enters a low−consumption shutdown mode.
