Design Notes
For the ADUM4138BRWZ, maintain proper creepage and clearance distances on the PCB to meet the 5000Vrms isolation rating. Use a minimum of 8mm creepage between input and output sides. Place the transformer for the flyback controller close to the IC to minimize parasitic inductance. Follow the layout guidelines in the datasheet for optimal performance.
The ADUM4138BRWZ can dissipate significant power when driving large IGBTs at high frequencies. Ensure adequate thermal management by providing a copper pour under the IC and using thermal vias to the ground plane. The SOIC-W package has a thermal resistance that should be considered; refer to the datasheet for thermal data and derating curves.
A common pitfall is neglecting the flyback transformer design. The integrated flyback controller requires a properly designed transformer with appropriate turns ratio and isolation rating. Use a transformer with low leakage inductance to minimize voltage spikes. Also, ensure the input supply is adequately decoupled with a 0.1uF ceramic capacitor close to the VDD1 pin.
Compliance Information
