Beschreibung
This reference design is an open-loop LLC converter, which provides four 18-V and 2.5 V outputs and up to 2.4 W for onboard charger applications. UCC25800-Q1 is used as the controller. LLC topology allows the transformer to have significant leakage inductance, but a much smaller primary-secondary capacitance, which significantly reduces common-mode current injection through the bias transformer.
