So I picked up a few of these little drivers on ebay which are setup for constant voltage regulation. After looking at the datasheet, I noticed a few feature I would like to figure out and modify.
Attached is the best macro I can take, but covers most of the traces aside from the input cap at the bottom and output cap at the top of the frame. The bottom of the board appears just to be gnd so all of the main connections to the IC are shown in this pic.. https://www.electronicspoint.com/at...5/?temp_hash=d1db38bfef2420f7ba91de9dadab050e
I would like to have the ability to do the following:
-control the soft start function / set the delay
-set the maximum output current / preferably with an external trimmer
-set the freq if possible to control pulsing / ^ not a priority like the above 2
The datasheet for it > http://pdf1.alldatasheet.com/datasheet-pdf/view/551593/MPS/MP1584EN.html
Now this driver is sold as a constant voltage source, but the datasheet indicate internal current regulation. Am I correct that changing the resistance value to pin 3 -comp- will set the current? and which pin and component would I change or alter to control the soft start function?
