LT6110 Cable/Wire Drop Compensator Fea T Descrip T n Improve Voltage Regulation to a Remote Load by 10 The LT 6110 is a precision high side current sense with a n Ideal for Resistor-Adjustable Voltage Regulators current mode output, designed for controlling the output n Gain Configurable with a Single Resistor voltage of an adjustable power supply or voltage regulator. n High Side Current Sensing: This can be used to compensate for drops in voltage at Integrated 20m Sense Resistor for Up to 3A a remote load due to resistance in a wire, trace or cable. Ability to Use an External Sense Resistor The LT6110 monitors load current via a series-connected n 300V Maximum Input Offset Voltage internal or external sense resistor. Two current mode out- n Output Current Accuracy of 1% Maximum puts, one sinking and one sourcing, are provided that are n 30A Maximum Supply Current proportional to the load current. This allows the LT6110 to n 2V to 50V Supply Range adjust the output voltage of a wide variety of regulators. n Fully Specified from 40C to 125C Either output may be used to monitor the load current. n Available in Low Profile (1mm) ThinSOT and Low DC offset allows for the use of a small sense resis- (2mm 2mm) DFN Packages tor, as well as precise control of small variations in wire voltage drop. a T L, LT, LTC, LTM, Linear Technology, the Linear logo and Module are registered trademarks and ThinSOT is a trademark of Linear Technology Corporation.
