STMicroelectronics STEVAL-VP319X1B Converter Evaluation Board
STMicroelectronics STEVAL-VP319X1B Converter Evaluation Board implements a 5V/3W Buck converter developed for general-purpose applications from 85VAC to 265VAC. If the size of the input bulk capacitors is increased, the evaluation board can supply the 3W in an extended range (40VAC to 265VAC). The reference design is built around the VIPERP319X, an offline high-voltage converter of the VIPERPlus family with 800V avalanche-rugged Power MOSFET, PWM current-mode control, fixed 30kHz switching frequency with jittering to satisfy electromagnetic disturbance standards, and burst mode for light load management.
The main features of the evaluation board are small size, minimal BOM, high efficiency, and low stand-by consumption.
