    LT6110
    Cable/Wire Drop
    Compensator
    Features Description n n n The LTВ®6110 is a precision high side current sense with a
    current mode output, designed for controlling the output
    voltage of an adjustable power supply or voltage regulator.
    This can be used to compensate for drops in voltage at
    a remote load due to resistance in a wire, trace or cable. Improve Voltage Regulation to a Remote Load by 10Г—
    Ideal for Resistor-Adjustable Voltage Regulators
    Gain Configurable with a Single Resistor
    High Side Current Sensing: Integrated 20mΩ Sense Resistor for Up to 3A Ability to Use an External Sense Resistor
    n 300ВµV Maximum Input Offset Voltage
    n Output Current Accuracy of 1% Maximum
    n 30ВµA Maximum Supply Current
    n 2V to 50V Supply Range
    n Fully Specified from –40°C to 125°C
    n Available in Low Profile (1mm) ThinSOTв„ў and
    (2mm Г— 2mm) DFN Packages
    n Applications The LT6110 monitors load current via a series-connected
    internal or external sense resistor. Two current mode outputs, one sinking and one sourcing, are provided that are
    proportional to the load current. This allows the LT6110 to
    adjust the output voltage of a wide variety of regulators.
    Either output may be used to monitor the load current. ...

    Control the Voltage of a Remote Load Over Any Length
    of Copper Wire – Design Note 529
    Philip Karantzalis
    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 regulator’s ground, two wires are required, one to the load ...

    Compensate for Wire Drop to a Remote 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 regulator’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 regulator’s output by an
    amount equal to VDROP. An LT6110 cable/ Figure 1. No extra wires are required to compensate ...
