2-Wire Virtual Remote Sensing for Voltage Regulators - Clairvoyance Marries Remote Sensing &mdash AN126
PDF, 1.4 Mb, File published: Oct 1, 2010
Wires and connectors have resistance. This simple, unavoidable truth dictates that a power source’s remote load voltage will be less than the source’s output voltage. Traditional methods for countering this include increasing the power source voltage and "4-wire" remote voltage sensing. Both have limitations. A new IC based approach achieves "virtual" remote sensing at the load without adding the usual two extra sense wires. Numerous circuit examples show the IC working with various voltage regulators and remote loads. Appendices detail IC internal operation and design guidelines for applying the part in any regulator circuit.

2-Wire Virtual Remote Sensing for Voltage Regulators
Clairvoyance Marries Remote Sensing
Jim Williams, Jesus Rosales, Kurk Mathews, Tom Hack
Introduction
Wires and connectors have resistance. This simple, unavoidable truth dictates that a power sourceвЂ™s remote load
voltage will be less than the sourceвЂ™s output voltage. Figure 1
shows this, and implies that intended load voltage can
be maintained by raising regulator output. Unfortunately,
line resistance and load variations introduce uncertainties,
limiting achievable performance.
