In this article I continue my project where I needed a constant current source. In the previous article I talked about the first approach the LM317 constant current source which didnít worked out that well but could of been improved as suggested by some of my readers in the comments. So I decided to use a dc-dc converter and turn it into a constant current source. Since Iím using the TPS54232 in another project and I have it around I decided to use it. This technique can also be applied to other dc-dc converters with a bit of reading on the subject.
