VIPERGAN100 Datasheet Advanced quasi-resonant offline high voltage converter with E-mode GaN HEMT Product status link VIPERGAN100 Product label Figure 1. Typical application Features Quasi-resonant (QR) flyback controller 650 V E-mode power GaN transistor Embedded sense FET Dynamic blanking time and adjustable valley synchronization delay functions, to maximize efficiency at any input line and load condition Valley-lock to ensure constant valley skipping Advanced power management for less than 30 mW standby power consumption with adaptive burst-mode Output OVP protection Input voltage feed-forward compensation for mains independent OPP variation Brown-in and brown-out protection Input OVP protection Embedded thermal shutdown Frequency jitter for EMI suppression Application High efficiency power adapters Fast battery chargers Auxiliary power supply for appliances, industrial, consumers, lighting Description The VIPERGAN100 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 75 W in wide range and up to 100 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 quasi-resonant operation with the dynamic blanking time feature and the valley synchronization function,...
