TPS84410: TPS84410

Part Number: TPS84410
Other Parts Discussed in Thread: TPSM82480, TPSM82810

I tried creating a footprint for this part but the datasheet is obviously wrong. It shows the distance between pad 1 and pad 2 is 1.45mm but when I do that the pads overlap. Please advise.

    Hi Todd,

    Can you please clarify where the error is?  I see a 1.45mm dimension on the land pattern drawing on page 32, but this distance is the distance from the center of pin 1 to the center of pin 2 (actually, the dimension is on pin 19 and pin 20 but it also applies to pin 1 and 2).  Taking half of the 0.6mm width of pin 2 and half of the 1.7mm width of pin 1, I get 1.15mm.  This leaves 0.3mm between the 2 pins.

    We also offer the footprint here:

    Finally, why do you use this older, larger module?  We have the newer, much smaller TPSM82810 and TPSM82480.

    Thanks,

    Chris
