Hi I am using MP2639A in one of my project . When i supply 5 volt input it does not start charging but as soon as I reduce the input to 4.7v it starts charging with low current. Here is my circuit diagram. Please help
Here is the reference schematic that is reflected in our EVB:
It seems for the most part, you follow this design as you are working in charge mode. You should be seeing a charge current of 2A according to the way this schematic is configured. Of course, please double check if there is anything that I missed between this reference schematic and your own schematic.
Do you have the layout files to supplement this IC with? Let me know.
Best,
Krishan
Hi Yes I have layout files as well. I can share the full project if you want. Please let me know which format is ok for you.
