TPS62441: kΩ in the equation of switching frequency in datasheet

Ernest Yong

Part Number: TPS62441

Hi Team,

There is a kΩ in the equation of switching frequency for different compensation setting. Would like to know what does the "kΩ" refer to?

Please kindly advise.

Many thanks!

Best Regards,

Hi Ernest,

The "kΩ" is part of the unit for 18 and 60 (MHz•kΩ) in Comp setting equations above. See sample calculation below.

RCF (kΩ) = (18 MHz•kΩ / 2.25 MHz) - 0.18 kΩ = 8 kΩ - 0.18 kΩ

RCF = 7.82 kΩ

I hope I was able to address your queries.

Best regards,
