STEVAL-VP318L1F

STEVAL-VP318L1F is a reference design that implements a 18W SSR isolated flyback converter developed for general purpose applications. The design is built around the new VIPer318L offline high-voltage converter from the VIPerPlus family with 800 V 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 stand-by 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.

• Universal input mains range from 85 to 265V AC
• Frequency range from 50 to 60Hz
• 15V output voltage
• 1.2A output current
• Stand-by mains consumption less than 55mW at 230V AC
• Average efficiency is greater than 85%
• Tight line and load regulation
• Meets IEC55022 Class B conducted EMI
