Differential Remote Sense
www.ti.com................................................................................................................................................... SLTS261C – MAY 2006 – REVISED SEPTEMBER 2009
The remote sense pins allows the converter to precisely regulate the DC output voltage at a remote location.
This might be a power plane on an inner layer of the host PCB. Connecting Sense(+) directly to +VO, and
Sense(–) to –VO will improve output voltage accuracy. In the event that the sense pins are left open-circuit, an
internal 10-
resistor between each sense pin and its corresponding output prevents an excessive rise in the
output voltage. For practical reasons, the amount of IR voltage compensation should be limited to 0.5 V
maximum.
The remote sense feature is designed to compensate for limited amounts of IR voltage drop. It is not intended to
compensate for the forward drop of a non-linear or frequency dependent components that may be placed in
series with the converter output. Examples of such components include OR-ing diodes, filter inductors, ferrite
beads, and fuses. Enclosing these components with the remote sense connections effectively places them inside
the regulation control loop, which can affect the stability of the regulator.
