STEVAL-VP318L1F SSR Flyback Converter Reference Design

STMicroelectronics' 15 V / 1.2 A SSR flyback converter is based on the VIPer318L HV converter

Image of STMicroelectronics STEVAL-VP318L1F SSR Flyback Converter Reference DesignSTMicroelectronics' compact 15 V / 18 W SSR isolated flyback converter evaluation board features universal 85 VAC to 265 VAC input, minimal BOM, high efficiency, low stand-by consumption, tight line and load regulation, and configurable input overvoltage and undervoltage protections. The design is based on the VIPer318L offline high-voltage converter with 800 V avalanche-rugged power MOSFET, PWM current-mode control, fixed 60 kHz switching frequency with jittering, and burst mode for light load management.

Features
  • Universal input mains range: 85 VAC to 265 VAC
  • Frequency: 50 Hz to 60 Hz
  • Output voltage: 15 V
  • Output current: 1.2 A
  • Stand-by mains consumption: <55 mW at 230 VAC
  • Average efficiency: >85%
  • Tight line and load regulation over the entire input and output range
