The STMicroelectronics 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 VIPER Plus 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.

Input power consumption in no load condition: < 16 mW at 230VAC

4-point average active mode efficiency at full load: > 69.7%

4-point average active mode efficiency at 10% full load: > 60.58%

Meets IEC55022 Class B conducted EMI
