93% Full-load efficiency (60% at 125mW): 310W industrial AC/DC reference design
Description
This reference design is a compact and high efficient two-stage power supply. The front-end stage is a CCM power factor correction (PFC) based on UCC28180.The second stage is based on UCC256304: which drives a resonant 310 W LLC converter with two outputs: 19 V and 56 V. The board does not need any auxiliary supply and draws only 250 mW from mains (with PFC off): while supplying 150 mW load.
Features
- High-efficiency 310W isolated power supply with PFC and resonant LLC stagesLow no-load power consumption without using auxiliary supply93% full-load efficiency at 230-Vac input; it draws only 250mW while supplying 150 mW loadCompact board with integrated heat sinks
