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 reinforced isolation of AC-DC off-line application between the primary and the secondary, operating from a DC source of 390 V. The EVM uses the UCC25600 resonant half-bridge controller which integrates built-in state of the art efficiency boost features with high level protection features to provide cost effective solutions for LLC resonant half-bridge converter applications. The secondary side uses two daughter cards, HPA410, with diodes to make rectification.
