Universal Input: 360W PFC + LLC with Combo-IC Reference Design
Description
This power supply reference design consists of a synchronous-rectification LLC isolated half-bridge associated to a CCM PFC stage. It needs 14V-primary (100mA max.) and 7V-secondary (50mA max.) as bias supply. Thanks to low-profile construction (20mm height): it can be employed in LCD screen applications: as well in high-efficiency and low dissipation cases thanks to efficiency values of 98% on PFC (high line) and 96% (97% peak) on LLC stage.
Features
- High efficiency on both stages: 96% (low line): 98% (high line) on PFC stage and 96.5% efficiency (at nominal 385Vin) on LLC stageA single thermal-shunt simplifies the interface with housingLow profile: 20mm: small form factor 142mm x 157mm
Applications
- Rack & server PSU with 48-V output
- Standalone avionics PFC
- Programmable DC power supply
