STEVAL-VP319X1B

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 3W in extended range (40 – 265VAC). The reference design is built around the new VIPERP319X, an offline high-voltage converter of the VIPERPlus family with 800V 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.
