VIPERGAN100TR

VIPERGAN100TR is a high voltage converter, designed for medium power quasi-resonant ZVS (zero voltage switching at switch turn-on) flyback converters, capable to provide an output power of up to 75W in a wide range and up to 100W in the European range or with 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 quasi-resonant operation with the dynamic blanking time feature and the valley synchronization function, which 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. Application includes high-efficiency power adapters, fast battery chargers, and auxiliary power supply for appliances, industrial, consumers, lighting.
