Operating Notes:

As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 5A at 5V (25W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 2.4V (12W/5A).
