The UCC256302 is a fully featured LLC controller with integrated high-voltage gate driver. It has been designed for use in offline AC-DC or isolated DC-DC to provide a complete power system using a minimum of external components. The resulting power system is designed to meet the most stringent requirements for standby power without the need for a separate standby power converter.

UCC256302 includes an integrated, high voltage startup function which eliminates the need for an external bias supply, reducing BOM count and minimizing solution size. UCC256302 uses hybrid hysteretic control to provide best in class line and load transient response. The control makes the open loop transfer function a first order system so that it’s very easy to compensate.

UCC256302 provides a high efficient burst mode with consistent burst power level during each burst on cycle. The burst power level is programmable and adaptively changes with input voltage, making the optimization of efficiency very easy.
