Controller eliminates remote sense wires

摘要

The LT4180 virtual remote-sense dc/dc controller eliminates the remote-sense wires required to compensate for the voltage drop in cables, wires, and circuit board trace runs. It continuously interrogates the line impedance and corrects the regulator's output voltage. The device maintains a corrected regulated voltage at the load regardless of current or line impedance. The 3 to 50-V input voltage range addresses remote instrumentation, battery charging, wall adaptors, notebook power, surveillance equipment, and halogen lighting applications.
