Fully Digital-controlled Power Supply Control IC with Bridgeless PFC and LLC Current-resonant Circuits
Data Sheet
Description
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 IC incorporates current mode for controlling constant voltages in the LLC stage and a floating drive circuit that drives an external high-side power MOSFET, in addition to functionally-rich protections. These digitally controlled strategies allow application-specific optimal settings. pared to conventional analog control circuits, the IC can achieve more cost-effective, high-efficient, yet low-noise power systems with fewer external ponents.
