Design Notes

Ensure adequate decoupling on both VDD1 and VDD2 supplies. Place 0.1 uF ceramic capacitors as close as possible to the supply pins, and a 10 uF bulk capacitor on each supply to handle transient currents during switching. The 4 A peak output current can cause significant supply droop if decoupling is insufficient.

Maintain proper creepage and clearance distances on the PCB to meet the isolation rating. For 3000 Vrms isolation, a minimum creepage of 4 mm is recommended for reinforced insulation. Use a slot or barrier under the device to increase creepage distance if needed.

Keep the gate drive loop (output pins to the power switch gate and source) as short as possible to minimize parasitic inductance. This reduces voltage overshoot and ringing, improving switching performance and reducing EMI. Use wide traces for high current paths.
