STMICROELECTRONICS EVLVIPGAN65DF Reference Design Board, VIPERGAN65D, Off-Line High Voltage Converter

EVLVIPGAN65DF is a 24V / 65W reference design set in isolated QR flyback topology, based on the VIPERGAN65D high-voltage converter. This controller combines, in the same package, a low-voltage PWM controller chip with a 700V GaN HEMT and integrates: a complete set of features which help design high-efficiency and low-standby consumption SMPSs with a short bill of materials, for cost-effective and fast design: ZVS quasi-resonant operation with dynamic blanking time; feedforward compensation; valley synchronization adjustment; low quiescent current; advanced light load management. A complete set of protections that considerably increases end-product�s safety and reliability: output overvoltage protection (OVP), output overload/short-circuit protection (OLP), brown-in/out protection, input overvoltage protection (iOVP). Suitable for high-efficiency auxiliary power supply for appliances, industrial and consumers applications.
