Dear Community members,

I have desgined a custom mkw36z board based on the schematics available in FRDM-KW36 Minimum BoM Development Board User’s Guide.

My design is exactly the same for buck mode auto start mode.

When I power up the board there is no voltage output from the dcdc converter.Neither 1v5 nor 1v8 is availbale on the relevant pins.

Attached is my schematics.

Any ideas to get the board running?

Thanks

Hi,

 

Hope you are doing well. The section of your schematic related to the DCDC seems to match the User Manual on which you based your design.

 

We have the Hardware Design Considerations for MKW35A/36A/35Z/36Z Bluetooth Low Energy Devices where you can find for example the layout and tracing recommendations.

 

And also I would recommend to check your board's physical connections (the soldering of your components).

 

Best Regards,

Ricardo
