1.3 Considerations

All tests were performed at room temperature on an open bench.

Use additional bulk input capacitors at low input voltage if there are long wires to the power source. Otherwise, input filter oscillation may occur due to the wiring inductance.

At sustained load, airflow or a heat sink attached to the bottom of the board is required, especially at low input voltage.
