NCP1901 Datasheet - ON Semiconductor

NCP1901 Primary Side Combination Resonant and PFC Controllers

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. A constant current source supplies current from this pin to the VCC capacitor, eliminating the need for an external startup resistor. The charge current is 7.5 mA .

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
