Remote Sense
The remote sense inputs (O
UTSENSE
+ and O
UTSENSE
-) should be connected to the load, using separate
sense traces on the system board as shown in Figure 42. Remote sense can compensate for the total output
voltage drop by up to the amount indicated in Table 6. These values are calculated to prevent unwanted
overvoltage protection by the module under the worst possible voltage error listed in Table 3 (including
transient error). In the event of an open remote sense lines, the module will maintain local sense regulation
through 100
Ω internal resistors connected to the V
OUT pins, with an additional + 0.3% DC error in V OUT .
