LSF0108-Q1: About Layout Guidelines

Part Number: LSF0108-Q1

Hi TI-team

My customer is considering this IC.

There is the following comment on P.15 of the data sheet.

Place LSF close to high voltage side.

What is the reason for this ?

They use two boards, one for MCU (5V) and one for Bluetooth (3.3V).

It cannot be installed on the same board due to radio waves, etc.

Is it better to mount this IC on the MCU board side ?


Best Regards,

Koji Hayashi
