24V/12W Off-Line DCM Flyback Converter Optimized for Zero-Power at No-Load

Overview

TopologyFlyback Converter
Input voltage85-265 V
Switching frequency0.2-50 kHz
Output 124 V / 0.5 A

Description

This design features the UCC28730 flyback controller in conjunction with the UCC24650 Wake-Up monitor to provide CV, CC regulated output with ultra-low stand-by power that exceeds Level VI and CoC Tier 2 specifications for average efficiency and 10% load efficiency. Wake-up signal detection provides fast transient response to large load steps.
