Fully Digital-controlled Power Supply Control IC with

Bridgeless PFC and LLC Current-resonant Circuits

MD6752S

Data Sheet

Description

Package

The MD6752S 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. Compared to

conventional analog control circuits, the IC can achieve

more cost-effective, high-efficient, yet low-noise power

systems with fewer external components.
