LM5141-Q1: slew rate control

Minqi Zhao

Part Number: LM5141-Q1

Dear experts,

My customer is using LM5141-Q1, and have confusions about slew rate control.

It is said that this control enables user to adjust and reduce EMI, but I can't find details about how to use this control and how to adjust. Does it mean changing gate resistor to see the impact of slew rate, and do we have calculator file about how to design slew rate to meet the EMI demand?

Thanks for your support.

Hello Minqi,

The driver slew rate control is the ability to independently adjust the rise and fall times of the Vsw node by planing differing Rgates for sourcing and sinking gate drive currents.

If you need more information, I have an NDA presentation I can share with you if you like?

Hope this helps?
