Other Parts Discussed in Thread: TPS543B22

I received an E-mail with a link to the Analog Design forum.

There was a newsletter with several chapters.

Is there some place to download the entire issue, rather than 8 separate articles?

There was this interesting article, but in it there is no schematic given for the filter they talk about, and I can't discern what it is from the board layout picture.

Am I missing something?

Clyde,

We used the schematic of the TPS543B22 evaluation module. The PCB also has pads for the second stage filter on the circuit board to be populated. Here is the link for the user's guide which has the schematic: TPS543B22EVM.

Regards,

Rich

I guess I can't see which components are the second stage filter in the UG.

Clyde,

The web has a photo of the EVM. The bottom middle connector is the output for the second stage. You'll see 2ND_PGND and VO_2NDSTG top side markings. You'll see L3, L4, C28-C31 which are not populated, but the filter goes there.

Regards,

Rich
