POINT OF LOAD 0.8V to 23V 3A

Description

This board with 25x45mm dimensions should be used as universal DC/DC, on a bread or prototype boards, on a box ....

It allows to convert an input voltage up to 24V with an efficiency up to 95% :
- Input Voltage : 4.5V to 24V.
- Output Voltage : 0.8V to 23V (fixed at 5V here).
- Max current : 3A.

PCB

The board dimensions are 25x45mm, as the PCB prototype standard dimensions are 100x100mm, it contains 4 POL boards.

So you have to cut the PCB on the red line.
