UCC25630-1DDBT Information

UCC256301 LLC Resonant Controller

Texas Instruments UCC256301 LLC Resonant Controller comes with an integrated high-voltage gate driver. The device has been designed to pair with a PFC stage 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, and with PFC stage running all the time. The UCC256301 includes a range of features designed to make LLC converter operation well controlled and robust. This device aims to unburden the LLC designer and allow mainstream applications to benefit from efficiency advantages of the LLC topology. The UCC256301 uses a hybrid hysteretic control to provide best in class line and load transient response. The control effort is approximately linearly proportional to the average input current in one cycle. This control makes the open loop transfer function a first order system so that it’s very easy to compensate. The system is always stable with proper frequency compensation.
