NCP1901 Primary Side Combination Resonant and PFC Controllers

NCP1901 Description

NCP1901 Advance Information Primary Side Combination Resonant and PFC Controllers The NCP1901 is a combination of PFC and half *bridge resonant.
20 Pin 1 16 Pin 1 Name HV Description This is the input of the high voltage startup regulator and connects directly to the bulk voltage.

NCP1901 Features

* needed to implement a highly efficient and small form factor adapter. It integrates a critical conduction mode (CrM) power factor correction (PFC) controller and a half
* bridge controller with a built
* in 600 V driver. The half
* bridge stage operates at a fixed frequency. Regula
