LT4180

Virtual Remote Sense

Controller

FEATURES

DESCRIPTION

The LT^®4180 solves the problem of providing tight load

regulation over long, highly resistive cables without

requiring an additional pair of remote sense wires. This

Virtual Remote Sense™ device continuously interrogates

the line impedance and corrects the power supply output

voltage via its feedback loop to maintain a steady voltage

at the load regardless of current changes.

Tight Load Regulation with Highly Resistive Cables

without Requiring Remote Sense Wiring

Compatible with Isolated and Nonisolated Power

Supplies

1ꢀ Internal Voltage Reference

5mA Sink Current Capability

Soft-Correct Reduces Turn-On Transients

Undervoltage and Overvoltage Protection

The LT4180 is a full-featured controller with 5mA opto-

isolator sink capability, under/overvoltage lockout,

soft-start and a 1ꢀ internal voltage reference. The

Virtual Remote Sense feature set includes user-program-

mable dither frequency and optional spread spectrum

dither.

Pin-Programmable Dither Frequency

Optional Spread Spectrum Dither

Wide V Range: 3.1V to 50V

24-Pin SSOP Package

APPLICATIONS

The LT4180 works with any topology and type of isolated

or nonisolated power supply, including DC/DC converters

and adjustable linear regulators.

12V High Intensity Lamps

28V Industrial Systems

High Power (>40 Watts) CAT5 Cable Systems

Wiring Drop Cancellation for Notebook Computer

Battery Charging

AC and DC Adaptors
