TYPICAL APPLICATION
FEATURES
DESCRIPTION
Virtual Remote Sense
Controller
The LT4180 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.
The LT4180 is a full-featured controller with 5mA opto-
isolator sink capability, under/overvoltage lockout,
soft-start and a ±1% internal voltage reference. The
Virtual Remote Sense feature set includes user-program-
mable dither frequency and optional spread spectrum
dither.
The LT4180 works with any topology and type of isolated
or nonisolated power supply, including DC/DC converters
and adjustable linear regulators.
The LT4180 is available in a 24-pin, SSOP package.
