LM2576: Alternative of LM2576 that uses a low ESR capacitor

Part Number: LM2576
Other Parts Discussed in Thread: LMR51430

Hi,

If the ESR of the LM2576's output capacitor is less than 0.03Ω, it will malfunction. Moreover, if it is larger than that, the performance of the power supply cannot be achieved. I'm looking for an alternative that uses a low ESR capacitor. Do you have any recommendations?

Thanks,

Conor

    Hi Conor,

    The newer version of this part, the LMR51430 does not seem to have any minimum ESR limitations. This may work for your use case.

    If this does not work, please send your input/output conditions for voltage/current and we would be happy to assist you there.

    Thank you,
