AND8184

The NCP1653 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction step−up pre−converters. AND8184 controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current.

Housed in a DIP8 or SO8 package, AND8184 minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NCP1653 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry.

Generally, the AND8184 is an ideal candidate in systems where cost−effectiveness, reliability and high power factor are the key parameters. It incorporates all the necessary features to build a compact and rugged PFC stage:
