NCP1901 - Primary Side Combination Resonant and PFC Controllers

Datasheet Summary

Description

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.

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. Regulation is achieved by adjusting the PFC stage output voltage. This device includes an enable input on the PFC feedback pin, open feedback loop protection and PFC overvoltage and undervoltage detectors.

NCP1901 Advance Information Primary Side Combination Resonant and PFC Controllers The NCP1901 is a combination of PFC and half−bridge resonant controllers optimized for off−line adapter applications. This device includes all the 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. Regulation is achieved by adjusting the PFC stage output voltage. This device includes an enable input on the PFC feedback pin, open feedback loop protection and PFC overvoltage and undervoltage detectors.
