STMicroelectronics STEVAL-VP318L1F Converter Evaluation Board
STMicroelectronics STEVAL-VP318L1F Converter Evaluation Board is a reference design that implements a 15V, 18W SSR isolated flyback converter developed for general-purpose applications operating from 85VAC to 265VAC. This design is built around the VIPer318L off-line high-voltage converter from the VIPerPlus family. This family comes with 800V avalanche-rugged Power MOSFET, PWM current-mode control, fixed 60kHz switching frequency with jittering to satisfy electromagnetic disturbance regulations, and burst mode for light load management.
The board features a small size, minimal BOM, high efficiency, low standby consumption, and tight line/load regulation over the entire input and output range. Input overvoltage and undervoltage protections with separate and settable trigger thresholds are available on the respective OVP and UVP pins.
