TPS65130: Basic layout advice

UD_Dave

Part Number: TPS65130

Hi Colleagues,

I have to use the TPS65130 to produce +5VDC & -5VDC from a 3 AA alkaline cell battery supply. The current requirement is << 50mA for each rail. The PCB will be 6 layers.

My question is this....Should I strive to put all the components on one side of the PCB or use both the top & bottom (component & solder side) layers?

Thanks & regards,

Dave

Hello Dave,

Please put all components on one side of the PCB. It is also crucial to follow the rules as described in the layout section of the d/s (Chapter 10), especially take care of the high switching and sensitive signals.

If you have more questions on the layout don't hesitate to post it here again.
Thank you.
Best Regards.

Hi Ilona,

Many thanks. I thought that would be the case.

I have near completed a first iteration of the layout. I will post it later today for your comments if you would so kind!

Best regards,

Dave

Ilona,

Hi again....I would like to send you this PCB design for your perusal. Screenshots do not look great. Is there any way I can send you the PCB design file (OrCad format). Or perhaps you could suggest another way of getting the design to you.

Thanks & regards, Dave
