Fully Digital-controlled Power Supply Control IC with Bridgeless PFC and LLC Current-resonant Circuits MD6751 Data Sheet Description 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 external high-side power MOSFET, in addition to its functionally-rich protections such as capacitive mode detection. These digitally controlled strategies allow application-specific optimal settings.
