STEVAL-VP22201B Data brief 5 V - 360 mA buck converter based on VIPer222XSTR Features Universal input mains range: 85265 V AC Frequency: 50-60Hz Output voltage: 5 V Output current: 360 mA Very compact size Stand-by mains consumption: < 18mW at 230 V AC 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-VP22201B evaluation board implements a 5 V - 1.8 W buck converter developed for general purpose applications operating from 85 to 265 V . AC The reference design is built around the VIPer222XSTR offline high-voltage converter from the VIPerPlus family, with 730 V Power MOSFET and PWM current- mode control. The main characteristics of the evaluation board are its small size and minimal BOM, low stand-by consumption and tight line and load regulation over the entire input and output range. Extremely low consumption under no-load condition is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes Product summary all frequency related losses. 5 V/360 mA buck STEVAL- converter based on VIPer222XSTR operates at 30 kHz fixed frequency with frequency jittering to enable VP22201B VIPer222 compliance with standards regarding electromagnetic disturbance. high performance, high voltage converter with embedded Power VIPer222 MOSFET and PWM control Buck and Buck- Boost Converters Applications Non-Isolated Auxiliary Power Supply up to 20W DB4123 - Rev 2 - June 2020 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-VP22201B Schematic diagrams DB4123 - Rev 2 page 2/6 1 Schematic diagrams Figure 1.
