Onsemi NCL30125 | Demoboard NCL30125
Fixed Frequency Current-Mode PWM Controller for Two Switch Forward topology
Overview
| Topology | Forward Converter |
| Input voltage | 176-264 V |
| Output 1 | 5 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
