Proper connection of the current Kelvin sense lines (SNSP, SNSN)

is important for current measurement accuracy. See Figure 24 for

an example layout of these Kelvin sense lines. The LTC9105 SNSP

and SNSN pins are Kelvin connected to the sense resistor pad

and are not otherwise connected in the power path. Figure 24

shows the two Kelvin traces from the LTC9105 to the sense resistor

(RSENSE).

RCLSA and RCLSB

Avoid excessive parasitic capacitance on the RCLSA and RCLSB

pins and place resistors RCLSA and RCLSB close to the LTC9105.

BYP Capacitor

Connect a 1μF ceramic capacitor from BYP to RTN as close as

possible to the LTC9105 package.
