FUJI
TRIPLE OUTPUT FLYBACK 3.5W DC-DC CONVERTER
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
