PSUs.pdf

Hi, I've attached a design schematic in file PSUs.pdf which uses TPS65632 to power an OLED screen.

I've also attached the Layout of it on a 4 layer board

Layout TPS.pdf

Can you please help review it? I'm not sure about how effective the layout is.

I'm trying to make it work through a microcontroller or a hand switched board.

Best Regards,

Hello Alex,

I reviewed your schematics/layout and it mostly looks reasonable. I would just suggest to not break the GND copper under the device by re-routing the trace shown below. Perhaps you can route toward south of the TPS65632 device instead of to the left that it is currently routed at. In general, try to keep the GND copper as much break free as possible.

Kind Regards,

Liaqat

Thanks Liaqat,

I tested the circuit on a PCB and indeed it looks like it's working fine (for the time being). I'll try routing it with unbroken ground on the next revision

Best Regards,

Alex
