Integrated LLC Controller 13-Pin ESIP-C

The HiperLCS is an integrated LLC power stage incorporating a multi-function controller, high-side and low-side gate drivers, plus two power MOSFETs in a half-bridge configuration. simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer. The variable frequency controller provides high-efficiency by switching the power MOSFETs at zero voltage (ZVS), eliminating switching losses
