STEVAL-VP319X1B - 5 V / 0.6 A Buck converter based on VIPER319X, STEVAL-VP319X1B, STMicroelectronics

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.
