Part Number: TPS62143
Other Parts Discussed in Thread: TPS62133,

Dear team,

I wish to know whether the TPS621433RGTT is fully replaceable with the TPS62133RGTT (pinout and layout means).

Best Regards,

Hi Itay,

Yes, these devices are pin to pin as noted on page 1 of the D/S. Just make sure your inductor can handle the increased current.

Hi Chris,

I've noticed that the exposed thermal pad's size is different on these two components.

Would it have any effect on the TPS62133 if it would be placed on the exact layout of the TPS62143?

Best Regards,

Itay

Thanks for explaining. In the D/S, it appears to be the same package drawing:

Where do you see a different thermal pad size?

The devices have the exact same package.

well it looks like all is in order!

I was using an old datasheet (June 2013) for the TPS62133, at which there was a slight exposed thermal pad area difference.

Thanks,

Itay
