The differential voltage input of the POL converter
feedback loop.
During normal operation the resistors are removed
from the circuit by the switches. The “Margining
Down” switch is normally closed shorting the resistor
R DOWN while the “Margining Up” switch is normally
open disconnecting the resistor R UP .
