- Fully digital-controlled PFC and LLC current-resonant circuits
- Soft start
- No lossy discharge resistor required with X capacitor
- Bridgeless PFC circuit
- Continuous Conduction Mode (CCM) PFC control
- Fully protected – Over voltage, over current, over-load, under voltage, thermal...
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.
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.
