TPS2660: TPS26601RHFR Can TPS26601RHFR inhibit EFT fast pulse group?

Hello Wang,

Can you please elaborate on below points for inhibiting EFT fast group?

What is frequency (5-kHz/100-kHz) and amplitude of EFT pulses 0.5/1/2-kV)?

Is it required to stop EFT pulses from passing through the device (IN to OUT)?

Hi Ti

One question :

The EFT waveform, as defined by the IEC 61000-4-4 standard,the testing involves injection of EFT pulses
into the equipment’s AC power supply lines. The EFT waveform can also be injected into the signal and control lines,
and earth connections to simulate the coupling of transient noise onto these lines, For detailed waveform parameters,

please refer to page 5 of annex.

Three question

Yes, EFT can cause system instability, so we need to restrain EFT from entering the system.
