LM5164-Q1: Datasheets show the same output resistances even though they are different currents

Anthony Wood

Part Number: LM5164-Q1
Other Parts Discussed in Thread: LM5163-Q1,

When comparing LM5164-Q1 with LM5163-Q1, there could be an errata since the first is 1000mA but the second is 500mA.

Both datasheets show 0.73 / 0.33 ohm for the output FETs, which doesnt seem likely!

Anthony,

The LM5164-Q1 and LM5163-Q1 are in the same family and use the same MOSFETs.

The LM5163-Q1 has a lower current limit setting for smaller inductors with lower saturation currents.

Let us know if you have further questions!
