APPLICATIONS INFORMATION
7. Minimize the capacitance between the SENSE pin trace
and any high frequency switching nodes. The LTC1871-7
contains an internal leading edge blanking time of ap-
proximately 180ns, which should be adequate for most
applications.
8. For optimum load regulation and true remote sens-
ing, the top of the output resistor divider should connect
independently to the top of the output capacitor (Kelvin
connection), staying away from any high dV/dt traces.
Place the divider resistors near the LTC1871-7 in order
to keep the high impedance FB node short.
