Description
This QR Flyback Evaluation Board uses an ICeGaN™ 650 V device with either 200 mΩ or 240 mΩ RDS(ON) as the primary switching transistor and uses ICeGaN´s integrated current sense feature in the current control loop.This topology highlights the No Load Power Consumption of ICeGaN, so crutial for products in this power range combined with state of the art switching performance togather with the thermal benefits ICeGaN current sense reducing power dissipation and reducing device temperature.
Features
- Using ICeGaN 650 V, 200 mΩ or 240 mΩ in DFN 5x6 Vin 100-260 VAC
- VIN 100-260 VAC
- VOUT 20 VDC
- Maximum Efficiency 93.8%
- Typical frequency range 25 ~ 240kHz
- No shunt current sense resistors – uses ICeGaN current sense feature
Typical applications
- SMPS applications
