TPS62065-Q1: Power Section Schematic Review

Rohan Singhal

Part Number: TPS62065-Q1

Creating a PCB for Car Geofencing. I'm specifically using automotive-grade IC(Q1). This is my power section that I have decided to use.

Please help me with the best layout practice for these power sections.
Also, important points(clearance and creepage) to be considered when using wireless communication modules like Quectel, MAX10S GPS, and BLE Modules on other side of PCB.
Other suggestions besides this are welcomed with open hands.

Input: 12V battery input(lead acid mostly) and additionally needed reverse voltage protection and transient voltage prot in 1st prototype.

Hello Rohan,

I will look at this request by tomorrow.

Thanks,

Hello Rohan,

I will recommend to have 10uF at input and 22uF at output. Because capacitor derates more at higher voltages.

Also we recommend R2 to be in between 120k to 360k.

For Layout:

I have already shared the guideline App note and also you can find the guidelines in device datasheet section 10.4.

Thanks,

Farheen

Actually, I designed this from WeBench
I thought it should copy it as it is.

Also, only changing the R2 directly will change my output. So how can I get a final schematic?
