Product overview
Description
The EVLVIPGAN65DF is a 24 V / 65 W 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 700 V 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 increase end-product’s safety and reliability: output overvoltage protection (OVP), output overload/short-circuit protection (OLP), brown-in/out protection, input overvoltage protection (iOVP).
To increase the system efficiency, the secondary side rectification is realized through a power MOSFET driven by the SRK1001 adaptive synchronous rectification controller.
