LM5141-Q1: Frequency dithering

Hi Dennis,

Recommended dithering frequency is close to the resolution bandwidth (RBW) of the measuring receiver as defined in the EMI specifications. This is 9-10kHz for emissions in the 150kHz to 30MHz range. Choose a DITH cap of 10nF for optimal EMI noise peak attenuation.
