Hello,
In order to reduce switching noise, my customer would like to put a resistor between BOOT pin and the 0.1uF cap connected to an L and SW pin. Is this practical? If yes, How much resistor range should it be?
Best regards,

Hi Hirano-san,
Typically in the single digit ohms and start with a smaller value and increase till the achieved level of ringing is achieved.
