330-W: 95.5% Efficiency and 18-W/in3 density: bridgeless PFC+LLC reference design
Description
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.
Features
- Full load efficiency at 230 V AC > 95.5% and >94% at 90 V ACHigh power factor > 0.99: meeting PFC regulations and current THD as per IEC 61000-3- 2 Class AZCS avoidance feature and OVP sensing feature in LLC controller improves robustness and protects systems from overcurrent: short circuit and overvoltage to ensure safetySmall 152 mm × 75 mm × 25 mm PCB form factor
