Description
The HiperLCS IC 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. Figure 1 (above) shows a simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer.
