LM2594: LM2594MX-3.3/NOPB

Part Number: LM2594
Other Parts Discussed in Thread: LM2574, LM2674, LM2675, LM22674, LM2672

Hello

Unfortunately, the LM2594MX-3.3/NOPB device is out of stock.

Which component can I use as an alternative without doing a redesign? The current may also be higher, e.g. 1A, the component should be pin-compatible so that it can be replaced 1 to 1. Is there an alternative?

Many Thanks

Best regards Thomas

  • Hello

    The LM2594 devices are bi-polar and do not require a boot strap capacitor.  All of the newer alternatives will require a boot capacitor

    and therefore a re-work of the PCB.  You might look at the LM2574; it is bi-polar.  Otherwise the newer devices requiring a boot cap

    are the LM2674, LM2761, LM2672, LM2675, LM22674; these are in the same package options.

    Thanks
