LLC Resonant Half-Bridge Conve

The UCC25600 evaluaTIon module, EVM (HPA341), is a 300-W LLC resonant half-bridge converter,providing a regulated output voltage nominally at 12 V at maximum 300 W of load power with reinforcedisolaTIon of AC-DC off-line applicaTIon between the primary and the secondary, operaTIng from a DCsource of 390 V. The EVM uses the UCC25600 resonant half-bridge controller which integrates built-instate of the art efficiency boost features with high level protection features to provide cost effectivesolutions for LLC resonant half-bridge converter applications. The secondary side uses two daughtercards, HPA410, with diodes to make rectification.
