The MD6752 is a fully digital-controlled power supply IC, which incorporates a bridgeless PFC control circuit and an LLC current-resonant circuit.

The PFC circuit, driven by continuous conduction mode (CCM), is controlled with frequencies suitable for applied input voltages and loads.

The LLC circuit incorporates a floating drive circuit that drives an external high-side power MOSFET, in addition to its functionally-rich protections such as capacitive mode detection.

The drive for energy conservation has led to more efficient controllers only possible using cycle-by-cycle digital control. The 3.5% typ. improvement in efficiency at 30% load equates to 30% less losses, and 20% reduction in the size of the power components.
