Control the Voltage of a Remote Load Over Any Length
of Copper Wire вЂ“ Design Note 529

Introduction
A common problem in power distribution systems is
loss of regulation due to the cable/wire voltage drop
between the regulator and the load. Any increase in
wire resistance, cable length or load current increases
the voltage drop over the distribution wire, increasing
the difference between actual voltage at the load and
the voltage perceived by the regulator. One way to
improve regulation over long cable runs is to measure
voltage directly at the load via a 4-wire Kelvin connection between the regulator and the load. Unfortunately,
this solution requires routing additional wires to the
load as well as a Kelvin resistor placed near the load,
impractical when the load is inaccessible for modification. Another method minimizes the voltage drop by
employing large diameter wire, lowering the resistance
from the regulator to the load. This is electrically simple,
but can be mechanically complicated. Increasing the
size of cable conductors can significantly increase
space requirements and cost. The LT6110 Cable/Wire Compensator
Figure 1 shows a 1-wire compensation block diagram.
If the remote load circuit does not share the regulatorвЂ™s ground, two wires are required, one to the load …

design ideas Compensate for Wire Drop to a Remote Load
Philip Karantzalis A common problem in power distribution systems is degradation of regulation due to the
wire voltage drop between the regulator and the load. Any increase in wire resistance,
cable length or load current increases the voltage drop over the distribution wire, increasing
the difference between voltage at the load and the voltage programmed by the regulator.
Remote sensing requires routing additional wires to the load. No extra wiring is required
with the LT6110 cable/wire drop compensator. This article shows how the LT6110 can
improve regulation by compensating for a wide range of regulator-to-load voltage drops.
THE LT6110 CABLE/WIRE
COMPENSATOR Figure 1 shows a 1-wire compensation
block diagram. If the remote load circuit
does not share the regulatorвЂ™s ground,
two wires are required, one to the load
and one ground return wire. The LT6110
high side amplifier senses the load current by measuring the voltage, VSENSE ,
across the sense resistor, RSENSE , and sinks
a current, IIOUT, proportional to the load
current, ILOAD. IIOUT scale factor is programmable with the RIN resistor from
10Вµ A to 1m A. Wire voltage drop, VDROP,
compensation is accomplished by sinking
IIOUT through the RFA feedback resistor
to increase the regulatorвЂ™s output by an
amount equal to VDROP. An LT6110 cable/ Figure 1. No extra wires are required to compensate …
