TPS548B28: Recommended maximum peak inductor current value formula

Roy Hsu

Part Number: TPS548B28

Hi, team

In TPS548B28 datasheet, the recommended maximum peak inductor current is 35A, is this value a calculated result? if yes, could you give me the formula?

Best Regards,

Hello Roy,

Please refer to datasheet section, 8.2.2.3 Choose the Inductor

The inductor also requires to add enough headroom above peak inductor current before saturation. The rule of thumb about 20%.

Thanks!
