LP8862-Q1: Inductor selection

Dharun Sangrithiyayan

Part Number: LP8862-Q1

HI TI!

I Have been designing a circuit for a LCD backlight driver using lp8862 .I 'm confused with the inductor selection part .

How can we determine the ripple current , is it 20-30% of inductor current?

Hi Dharun,

The recommended inductor is already recommended in the datasheet according to the different switching frequency.

Thanks, Charles!

So it doesn't depend on the ripple current.
