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 3A at 5V (15W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 4V (12W/3A).Package includes:1X 8V-23V Input to 5V Output 3A 15W USB-C DC-DC Step Down ConverterGet it faster!
