STMicroelectronics EVLVIPGAN65DF Reference Design for VIPERGAN65
STMicroelectronics EVLVIPGAN65DF Reference Design for VIPERGAN65 is a 24V/65W reference design set in an isolated QR flyback topology, based on the VIPERGAN65D high-voltage converter. This controller combines a low-voltage PWM controller chip with a 700V GaN HEMT in the same package. The device integrates a complete set of features that help design high-efficiency and low-standby consumption switch-mode power supplies with a short bill of materials, for cost-effective and fast designs. These designs include ZVS quasi-resonant operation with dynamic blanking time, feedforward compensation, valley synchronization adjustment, low quiescent current, and advanced light load management.
A complete set of protections is also included to considerably increase end-product safety and reliability: output overvoltage protection (OVP), output overload/short circuit protection (OLP), brown-in/out protection, and input overvoltage protection (iOVP). The secondary side rectification is realized through a power MOSFET driven by the SRK1001 adaptive synchronous rectification controller to increase system efficiency.
