LM2596 ADJ Vout drops with a Low Load

I have attached a Webench design for this output and some assumed inputs and load. The lime green wire that spans the proto-board from bottom to top is the input voltage line.

You may be running into current limit or duty cycle limits. I would hold off on buying the bigger inductor for now.

In reply lm25966 Laura Vorster: You may have to bend the leads a little and cut the leads of the through hole components short to fit on the PCB. Due to the holidays, responses may be delayed. In reply to Laura Vorster:.

The newly created question will be automatically linked to this question. When loaded down with a load of greater than 35 ohms the chip regulates the output voltage, but under 35 ohms the output voltage drops. The input voltage range is V.

Webench uses a much bigger inductor; you might want to try that. I have attached a Webench design.
