Power Integrations LCS703HG

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. The variable frequency controller provides high efficiency by switching the power MOSFETs at zero voltage (ZVS), eliminating switching losses.
