Beschreibung
This compact, high efficiency, 24V DC, 150W nominal, 240W peak output at 230VAC reference design is targeted for industrial AC/DC power supplies. The circuit consists of a frontend transition mode (TrM) power factor correction(PFC) circuit based on the UCC28056, followed by a robust LLC stage for an isolated DC/DC converter based on the UCC256301. For high efficiency needs, synchronous rectification is done with the UCC24624. This design does not need an additional auxiliary power supply to meet no-load consumption. The design enables 94% peak efficiency and allows the system to work without forced cooling. This design has both constant current(CC) and constant voltage(CV) feedback loop which is suitable for battery charger application.
Eigenschaften
- Wide operation input range of 90 to 265V AC with full power delivery over entire range
- Peak overall efficiency of 94.4% at 230V AC and 93% at 115V AC, enables natrual convection cooling
- Delivers up to 6.25A continuous current and up to 10A peak current for 3 seconds
- Adjustable output voltage from 22 to 28V
- Very low no load power consumption of <400mW
- System protected for overcurrent, short-circuit, and overvoltage ensuring safety needs
