Apr 8, 3: The schematic for my circuit is shown below. The lime green wire that spans the proto-board from bottom to top is the input voltage line.


In reply to Frank De Stasi:. No license, either express or implied, by estoppel or otherwise, is granted by TI.

If so that would give a Vout of I have attached a Webench lm259. The load in the picture is 1k.

Please send a snapshot of your layout. What is your input voltage range and load range? Why is it doing this? Webench uses a much bigger inductor; you might want to try that.

You may have to bend the leads a little and cut the leads of the lm596 hole components short to fit on the PCB. In reply to Laura Vorster:. I have attached a Webench design for this output and some assumed inputs and load.

Due to the holidays, responses may be delayed.

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 combined value is You may pm2596 running into current limit or duty cycle limits. TI is a global semiconductor design and manufacturing company.

I am not sure what your top FB resistor value is? We are glad that we were able to resolve this issue, and will now proceed to close this thread. Trademarks Privacy Policy Terms of Use. Locked Cancel Do you aej another question?

LM2596 ADJ Vout drops with a Low Load

We’re going to purchase the uH inductor to try that as you have suggested. L,2596 would hold off on buying the bigger inductor for now. There are two resistors being used for the FB resistor.
