Beschreibung
This reference design is a compact, high efficiency, bridgeless 330-W, 19.5-V output AC/DC reference design. This design consists of a front-end, bidirectional bridgeless boost power factor correction (PFC) based on the UCC28180A device, achieving end-to-end peak efficiency of > 94% at 90 V AC input and > 95.5% at 230 V AC input. The DC/DC is implemented using the HB-LLC stage implemented using our UCC256301 device. The design uses UCC24624 for synchronous rectification at the secondary side to improve efficiency.
Eigenschaften
- Full load efficiency at 230 V AC > 95.5% and >94% at 90 V AC
- High power factor > 0.99, meeting PFC regulations and current THD as per IEC 61000-3- 2 Class A
- < 0.25-W standby power with burst mode in both PFC and LLC stages
- ZCS avoidance feature and OVP sensing feature in LLC controller improves robustness and protects systems from overcurrent, short circuit, and overvoltage to ensure safety
- Small 152 mm × 75 mm × 25 mm PCB form factor
Typische Anwendungen
- Consumer AC / DC / DIN Rail Power Supply / Industiral AC / DC / PC Power Supply
