Measuring Bode plot

Jump to solution

Hello,

 

I have a question on the method used or suggested by Intel to measure bode plot on EN6337 or EN63A0 product. Is Intel use the "classical" way with resistor around 10 Ohms in serie on the feedback loop and a injection transformer or any other way?

 

Thanks

Hello MBaqu,

 

Yes, Intel/Enpirion uses the classic way to measure the bode plot for the power regulators.

Basickly, we insert a resistor (range from10Ohm to 50Ohm) in series with the feedback loop and inject the noise through that resistor and measure the bode plot.
