PMP23069: Output Ceramic Caps

Hello, C52 and C53 are on bottom layer

Hello Bosheng,

I have attached the screenshot of bottom layer planes

There seem to be a small isolation breaking the planes(rats can be seen as well):

If this is intentional, why are the C52 & C53 connections kept as optional?

Regards,

A GaN daughter is soldered in position 1, the daughter card already have caps for the same purpose of C52 and C53.  Position 2 is reserved for a different GaN daughter card, if it is used, then the isolation gap must be shorted. Only position 1 is used in the released PMP23069 board. 

Got confused with position 2 as testpoints (as mentioned in the schematic)

So no need to place C52 & C53 on the Mainboard(while using GaN card at position 1) Thanks for the clarification.

May I know which GaN card is compatible for position 2?

Regards,

Hello,

Is there a C2000 card option where the card fits inside the power supply region? (within 68.1mm)

Regards,

do you mean the length of the control card needs to < 68.1mm? 

I am talking about the mentioned width of the board

Is there a C2000 daughter card option that can be placed directly near J1 & J2?

Regards,
