UCC256302 LLC Resonant Controller

Texas Instruments UCC256302 LLC Resonant Controller is a fully featured LLC controller with an integrated high-voltage gate driver. This device has been designed for offline AC-DC or isolated DC-DC to provide a complete power system with minimum external components. The resulting power system is designed to meet the most stringent requirements for standby power without needing a separate standby power converter. The Texas Instruments 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 a hybrid hysteretic control to provide best-in-class line and load transient response. This control makes the open loop transfer function a first-order system, making compensating effortless.
