This reference design is a control card for an LLC converter and integrates all of the essential functions for controlling an LLC converter, including the HV start-up, X-capacitor discharge and the drivers for the power FETs. By employing the advanced burst mode, it can also help the LLC converter achieve ultra-low standby power even with PFC on. This design is flexible to evaluate and is suitable for any power rating of an LLC power board. It is easy to set up a bench test with an existing power stage with simple connections.
