Linear Technology LT4180IGN#TRPBF
- Part Number:
- LT4180IGN#TRPBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3268177-LT4180IGN#TRPBF
- Description:
- IC CTLR REMOTE SENSOR 24SSOP
- Datasheet:
- LT4180IGN#TRPBF
Description
The LT4180 is a Virtual Remote Sense™ device that solves the problem of providing tight load regulation over long, highly resistive cables without requiring an additional pair of remote sense wires. It 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-programmable 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.
Features
Tight load regulation with highly resistive cables without requiring remote sense wiring
Compatible with isolated and nonisolated power supplies
±1% internal voltage reference
5mA sink current capability
Soft-correct reduces turn-on transients
Undervoltage and overvoltage protection
Pin-programmable dither frequency
Optional spread spectrum dither
Wide VIN range: 3.1V to 50V
24-lead SSOP package
Applications
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
Well-logging and other remote instrumentation
Surveillance equipment
