Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 90-265 V |
| Switching frequency | 600 kHz |
| Output 1 | 385 V / 1 A |
| IC revision | A |
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
