Design Notes

Place input and output capacitors close to the module pins to minimize parasitic inductance. Use low-ESR ceramic capacitors (e.g., 10µF) for input and output. For high-current applications, multiple capacitors in parallel are recommended to handle ripple current.

The BGA-144 package has a thermal pad on the bottom. Ensure proper thermal vias and a copper pour on the PCB to dissipate heat. For 26A output, consider forced airflow or a heatsink to keep junction temperature within limits.

Keep the PMBus traces (SDA, SCL) short and away from high-current switching nodes to avoid noise. Add pull-up resistors (e.g., 4.7kΩ) to the PMBus lines. Route sense lines as differential pairs to the load for accurate voltage sensing.
