LLC Current Resonant power supply design tools

This design tool is a support tool for designing peripheral circuit values for current resonance power supply circuits using our LLC current resonance power supply IC MCZ series.
By entering conditions such as input/output power specifications, reference circuit diagrams and parts lists are automatically generated.In addition, the resonance curves required for designing the resonance conditions of the LLC current resonance circuit and the parameters for performing circuit simulation are also output.

Please make use of this when designing circuits using the MCZ series.
