linear DESIGN FEATURES LTJournal-V20N2-00-Cover-LT4180-Tom_Hack service manual
The article introduces the LT4180 controller and its technology, Virtual Remote Sensing (VRS), designed to solve voltage drop issues in power distribution systems. Conventional methods like remote sensing require extra wires, while local regulation is inefficient; VRS offers a flexible alternative by dynamically correcting for impedance.

Questions answered in these manuals
How does Virtual Remote Sensing measure voltage drops across wiring?
The system works by alternating the output current between 95% and 105% of the required output current to create a measurable square wave.

What is the maximum voltage drop at the load when a 2.5V wiring drop occurs?
When the wiring causes a 2.5V drop, the voltage at the load dropped only 73mV from its value at no current.

What is the peak-to-peak amplitude of the square wave current generated by the LT4180?
The LT4180 forces a small square wave current with a peak-to-peak amplitude equal to 10% of the DC current.
