LMR54406: Differences between LMR54406F and TPS560430XF

Part Number: LMR54406


I'm trying to determine the differences between LMR54406F and TPS560430XF as they look extremely similar.

So far I've found slight differences in Vref, Output voltage range, and recommended temp range. Is there anything else?



  • Hello Michael,

    I would view these devices as functionally equivalent for the most part.

    For the LMR544xx device family, the device is rated up to higher output power and ABSMAX on Vin changes.

    I would note the electrical characteristic differences between the two devices, in the case you are looking to change from one device to another in a given application and ensure the slightly different electrical characteristics is acceptable for the given application.
