STEVAL-VP12201F Data brief 12 V - 5 W isolated flyback converter based on VIPer122LS Features Universal input mains range: 85265 V AC Frequency: 50-60Hz Output voltage: 12 V Output current: 416 mA Highly compact size Stand-by mains consumption: < 30 mW at 230 V AC Average efficiency: > 77% Tight line and load regulation over the entire input and output range Meets IEC55022 Class B conducted EMI even with reduced EMI filter, thanks to the frequency jittering feature RoHS compliant Description The STEVAL-VP12201F evaluation board implements a 12 V - 5 W isolated flyback converter developed for general purpose applications supplied from 85 to 265 V . AC The reference design is built around the new VIPer122LS offline high-voltage converter from the VIPerPlus family, with embedded 730 V Power MOSFET and PWM current-mode control. The main characteristics of the evaluation board are its small size and minimal BOM, high efficiency, low stand-by consumption and tight line and load regulation over the Product summary entire input and output range. Extremely low consumption under no-load condition is ensured thanks to burst mode operation, which reduces the average switching 12 V/5 W power supply frequency and minimizes all frequency related losses. in isolated flyback STEVAL- topology featuring the VIPer122LS operates at fixed frequency 60kHz with frequency jittering to meet the VP12201F VIPer122 offline HV standards regarding electromagnetic disturbance. converter high performance, high voltage converter with embedded Power VIPER122 MOSFET and PWM control Isolated Auxiliary Applications Power Supply up to 20W DB4121 - Rev 1 - October 2020 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-VP12201F Standby consumption and efficiency 1 Standby consumption and efficiency Figure 1.
