The LT4180 virtual remote sense (VRS) controller is a new revolutionary way of eliminating the need for remote sense wires to compensate for the IR losses in cables and wiring. This device continuously interrogates the line impedance and corrects the power supply output voltage to maintain a steady voltage at the load regardless of current changes. VRS works with a small modulation on the output of the regulator to compute the correction. This modulation is filtered by an output capacitor at the load. The LT4180 works with any conversion topology, isolated or non-isolated power supplies, DC/DC converters including bricks, modules and adjustable linear regulators. The Drain pin from the LT4180 controls the feedback loop of the regulator.
