STEVAL-VP12201F Isolated Flyback Converters
STMicroelectronics' reference design board for a 12 V to 5 W isolated flyback converter is a general-purpose power supply
STMicroelectronics' reference design board for a 12 V to 5 W isolated flyback converter represents a general-purpose power supply for 85 VAC to 265 VAC mains inputs. The reference design is built around the VIPer122LS offline high-voltage converter with 730 V power MOSFET and PWM current-mode control. It is a highly compact solution requiring a minimal BOM, delivering high efficiency, low stand-by consumption, and tight line and load regulation over the entire input and output range. Burst mode operation ensures low consumption under no-load and fixed frequency operation with frequency jittering ensures compliance with strict EMI requirements.
