75W 5A DC-DC converter adjustable voltage with LED Display

Description

This is an assembled board of DC-DC converter module. It can offer 75W of power, and a maximum of 5A of current. It can be used as a standard power supply, or for audio application that do not have critical requirement on noise performance.

The board includes a 3 digital LED voltmeter to read the input/output(toggle by a button) voltage. The voltmeter error is +/-0.05V. The display can also be turned off by toggling another button.

The board includes a heatsink that can be attached to the DC-DC converter IC, and 4 pieces of standoff to mount the board onto chassis.
