AC-DC Active Clamp Flyback PWM Controller

Overview

TopologyFlyback Converter
Switching frequency100-1000 kHz

Description

NCP1568 is a highly integrated AC-DC PWM controller designed to implement an Active Clamp Flyback topology. NCP1568 uses a proprietary variable frequency algorithm to enable zero-volt switching on Super-Junction or GaN FETs across line and load conditions, allowing for increased power density and a larger range of options on design components. The NCP1568 is designed for a variety of applications including: AC-DC Adapters, Industrial, Telecom, and other high power density applications

Features

  • Active Clamp Flyback Topology
  • Multi-mode Operation
  • Programmable Control Scheme
  • Quiet Skip
  • Programmable Frequency

Typical applications

  • AC-DC Power Conversion, USB Power Delivery, Qualcomm Quick Charge
