LT4180

Virtual Remote Sense Controller

DESCRIPTION

Demonstration circuit 1504A features the LT4180, a virtual

remote sense controller which eliminates the need for

remote sense wires to compensate for IR losses in cables

and wires, and is used in conjunction with the LT3693

buck converter. The circuit is designed for an input voltage

range of 8V to 36V with an output of 5V at 3A. The circuit

board has a total wire resistance of 0.4Ω and a voltage

drop of 1.2V. The circuit contains five selectable jumpers.

JP1 turns the converter ON or Off, JP2-JP4 allow for easy

selection of other dither frequency combinations, and

JP5 enables or disables spread spectrum operation. The

LT4180 data sheet gives a complete description of the part,

its operation and application information. The data sheet

must be read in conjunction with this quick start guide for

working on or modifying the demo circuit 1504A.

QUICK START PROCEDURE

Demonstration circuit 1504A is easy to set up to evalu-

ate the performance of the LT4180. Refer to Figure 2 for

proper equipment setup and follow the procedure below.

When input or output voltage ripple is measured, care

must be taken to avoid a long ground lead on the oscil-

loscope probe. Measure the input or output voltage ripple

by touching the probe tip directly across the V

or V

and GND terminals. See Figure 2 for proper scope probe

technique.
