Onsemi NCL30125 | Demoboard NCL30125

Fixed Frequency Current-Mode PWM Controller for Two Switch Forward topology

Overview

TopologyForward Converter
Input voltage176-264 V
Output 15 V / 60 A

Description

The NCL30125 is a fixed frequency current-mode controller with integrated high voltage gate drivers. The HV pin allow a quick start-up with dynamic self supply (DSS) features. The skip cycle mode insures good efficiency in light load condition. And enable flexible & robust design with controllable soft-start time, switching frequency and various protections.

Features

  • Internal 700 V high side gate driver
  • Skip cycle mode
  • Dynamic Self Supply (DSS)
  • Internal 700 V HV startup current source
  • Frequency Jittering
  • 35 V wide VCC operation
  • Adjustable operating frequency & soft start duration
  • Optional features (Skip threshold, BO level, OCP timer & etc.)
  • Auto-recovery or Latch option
  • Brown-out, OCP(SCP/OLP), VCC OVP, TSD
  • Dedicated Fault pin for OVP or OTP detection

Typical applications

  • Industiral lighting
  • Lighting Advertisement power board
