  • The STEVAL-VP12201B evaluation board implements a 15 V-3 W buck converter mains designed for general purpose applications, operating from 85 to 265 VAC.

    It is built around the VIPER122 offline high-voltage converter of the VIPerPlus family with a 730 V Power MOSFET and PWM current mode control.
    The STEVAL-VP12201B features include its small size and minimal BOM, high efficiency, low standby consumption, and tight line and load regulation over the entire input and output range.
    Burst mode operation allows extremely low consumption under no load and reduces the average switching frequency to minimize all frequency related losses.
    VIPER122 operates at a fixed frequency of 60 kHz with frequency jittering to meet electromagnetic disturbance standards.

    Key Features

    • Universal input mains range: 85–265 VAC
    • Frequency: 50-60 Hz
    • Output voltage: 15 V
    • Output current: 200 mA
    • Very compact size
    • Stand-by mains consumption: < 30mW at 230 VAC
    • 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
    • WEEE compliant
    • RoHS compliant
