DC-DC Multi-Output Step-Down Buck Converter (3.3V/5V/9V/12V)

This compact DC-DC step-down converter converts input voltages from 7.5-30V into an output voltage of 3.3V/5V/9V/12V (standard is 5V). The output voltage can be changed by bridging the corresponding pads on the back. The module is designed for a load current of up to 5A. If a load current of over 3A is needed, we recommend installing a heat sink to prevent the module from overheating.  The module has a status LED, which lights up red during normal operation, and turns off when the protection mechanism is triggered and the voltage automatically drops to 0.1V.  For optimal operation, the input voltage should be approx. 2V higher than the desired output voltage. 

Info: This module outputs 5V by default and the respective 5V solder pad is short-circuited. To output other voltages, e.g. 3.3V, disconnect the 5V solder pad and short-circuit the 3.3V solder pad.
