Overview
| Topology | Flyback Converter |
| Input voltage | 100-260 V |
| Output 1 | 20 V |
| IC revision | 2.0 |
Description
This QR Flyback Reference Design uses our 240 mΩ ICeGaN 650 V device as the primary switching transistor and uses ICeGaN´s integrated current sense feature in the current control loop.This topology highlights the extremely low No-Load Power Consumption of ICeGaN, so crutial for products in this power range, combined with state of the art switching performance and the thermal benefits ICeGaN current sense reducing power dissipation and reducing device temperature.
Features
Using ICeGaN 650 V, 240 mΩ in DFN 5x6Power density of >27W/in3Vin 100-260 VACVout 20 VDCMaximum Efficiency 93.8%Typical frequency range 25 - 240kHzNo shunt current sense resistors – uses ICeGaN current sense feature
Typical applications
- PD chargers
