VIPERGAN65W Datasheet PDF

STMicroelectronics VIPERGAN65W

The VIPERGAN65W is a high voltage converter, designed for medium power quasiresonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters, capable to provide an output power up to 65 W in wide range and up to 85 W in European range or with a PFC in the front end. It integrates a complete set of features that provide an extremely flexible and easy to use chip and helps to design a highly efficient offline power supply. The ZVS quasiresonant operation with the dynamic blanking time feature and the valley synchronization function, that turns on the power switch always at the valley of the drain resonance, reduces the switching losses and maximizes the overall efficiency at any input line and load condition.
