MD6751 Fully Digital-controlled Power Supply Control IC

The MD6751 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 exter.
