STEVAL-VP319X1B: 3W, 5V @ 600mA, 85 ~ 265 VAC

Summary

The STEVAL-VP319X1B evaluation board implements a 3W, 5V @ 600mA Buck converter developed for general purpose applications, operating from 85 to 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.

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).

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
