8.4.1.3 CS Pin Signal

As seen with Equation 4, the current-sense signal impedance is three orders of magnitude higher than a traditional current-sense signal. This higher impedance has implications for current-sense signal noise susceptibility. Minimize routing the current-sense signal near any noisy traces. Place the current-sense resistor and any filtering capacitors at the far end of the trace next to the controller current-sense input pin.
