FUJI

TRIPLE OUTPUT FLYBACK 3.5W DC-DC CONVERTER

Product Image

The EVK-FUJI is a reference design for a non-isolated DCM Flyback DC-DC converter, with triple outputs. It is therefore a Point-of-Load solution suitable to generate 3 standard voltages from a single power supply input ranging from +12V to +28V. The default output voltage values are +5V; +3.3V and +1.8V; they can be modified to accommodate for different voltage needs.

Key features

  • ICs Operating junction temperature: -55°C to +225°C
  • Evaluation Board suitable for testing up to 200°C (excursions)
  • Vin range: +12V to +28V
  • Triple voltage output (customizable):
    • +5V / 400mA
    • +3.3V / 250mA
    • +1.8V / 250mA
  • Power range: 3.5W
  • Based on:
    • 1x PWM Controller CHT-MAGMA
    • 4x transistors CHT-NMOS8001
  • Up to 68% efficiency
  • Switching frequency: 100kHz (default); adjustable up to 500kHz




 


Applications

  • Embedded power supply blocks in down-hole tools
  • PoL in aeronautics and aerospace
  • High reliability DC-DC modules
