What is your input voltage range and load range? Go to Support forums. Do you have another question?

The input voltage range is V. Webench uses a much bigger inductor; you might want to try that. Please send your shipping address and a lm259 number to the following email: No license, either express addj implied, by estoppel or otherwise, is granted by TI. If so that would give a Vout of Apr 8, 4: Trademarks Privacy Policy Terms of Use. Due to the holidays, responses may be delayed.

Apr 8, 8: You may have to bend the leads a little and cut the leads of the through hole components short to fit on the PCB. When loaded down with a load of greater than 35 ohms the chip regulates the output voltage, but afj 35 ohms the output voltage drops.

LM2596 ADJ Vout drops with a Low Load

We are glad that we were able to resolve this issue, and will now proceed to close this thread. The combined value is You may be running into current limit or duty cycle limits.

I have attached a Webench design. Ask a related question What is a related question? We’re going to purchase the uH inductor to try that as you have suggested.


I would hold off on buying the bigger inductor for now. This thread has been locked. The output voltage I have attached a Webench design for this output and some assumed inputs and load. Ask a related question Ask a new question. Ask a new question Ask a new question Cancel. acj
