DescriptionThe UCC25630-2DDBT is a fully featured LLC controller with integrated high-voltage gatedriver. It has been designed for use in offline AC-DC or isolated DC-DC to provide a complete powersystem using a minimum of external components. The resulting power system is designed to meet themost stringent requirements for standby power without the need for a separate standby powerconverter.
UCC25630-2DDBT includes an integrated, high voltage startup function which eliminates the needfor an external bias supply, reducing BOM count and minimizing solution size. UCC25630-2DDBT uses hybridhysteretic control to provide best in class line and load transient response. The control makes theopen loop transfer function a first order system so that it’s very easy to compensate.
UCC25630-2DDBT provides a high efficient burst mode with consistent burst power level duringeach burst on cycle. The burst power level is programmable and adaptively changes with inputvoltage, making the optimization of efficiency very easy.
