Description

Description

The STEVAL-VP319X1B evaluation board implements a 5V/3W Buck converter developed for general purpose applications, operating from 85 to 265VAC.

If the size of the input bulk capacitors is increased, the evaluation board is able to supply the 3 W in extended range (40 – 265VAC).

The reference design is built around the new VIPERP319X, an offline high-voltage converter of the VIPERPlus family with 800 V avalanche-rugged Power MOSFET, PWM current-mode control, fixed 30 kHz switching frequency with jittering to satisfy electromagnetic disturbance standards, burst mode for light load management.

The main features of the evaluation board are: small size, minimal BOM, high efficiency, low stand-by consumption.

  • All features

    • Universal input mains range: 85–265VAC
    • Frequency: 50-60 Hz
    • Output voltage: 5 V
    • Output current: 0.6 A
    • Input power consumption in no load condition: < 16 mW at 230VAC
    • 4-point average active mode efficiency at full load: > 69.7% (compliant with European CoC ver. 5)
    • 4-point average active mode efficiency at 10% full load: > 60.58% (compliant with European CoC ver. 5)
    • Meets IEC55022 Class B conducted EMI
    • RoHS compliant
