Description

The UCC25640x is a fully featured LLC controller with integrated high-voltage gate driver. It has been designed to pair with a PFC controller 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.

UCC25640x provides a highly efficient burst mode with soft-on and soft-off periods to minimize audible noise at standby operation. The burst power level and hysteresis are programmable, simplifying the optimization of efficiency and burst mode operation. Burst mode can also be disabled through pin configuration. UCC25640x uses hybrid hysteretic control to provide best in class line and load transient response.

UCC25640x includes a range of features designed to make LLC converter operation well controlled and protected. It can be used with UCC28056 or UCC28064A PFC controllers, along with UCC24624 synchronous rectifier controller to offer a complete power supply solution.
