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 85 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 and 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.
