NCP1654 Description
Power Factor Controller for pact and Robust, Continuous Conduction Mode Pre-Converters NCP1654 The NCP1654 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction step−up pre−converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current. Housed in a SO8 package, the circuit minimizes the number of external ponents and...
