LM5164-Q1: Question about math symbol in the datasheet

Joonho Seo1

Part Number: LM5164-Q1

Hello, this might be a stupid and embarrassing question but I had to ask because I can't find any info about it.

I was looking at the datasheet and like equation(5) and equation(7), there is (R_FB1 || R_FB2).

What does it mean? Please let me know

Thank you in advance.

    hi, Joonho,

    Thank you for posing, that means the FB resistor on the top and bottom. This resistor is used for output voltage set refer to FB reference voltage .

    (R_FB1 || R_FB2)=(R_FB1 * R_FB2) /(R_FB1 + R_FB2)
