The device integrates a remote sense amplifier across the FB and GOSNS pins. The remote sense function compensates for voltage drop on the PCB traces helping to maintain V_OUT accuracy under steady state operation and load transient events. The V_OUT connection of the remote sensing signal must be connected to the feedback resistor divider with the lower feedback resistor, R_{FB_B}, terminated at the GOSNS pin.

The FB voltage divider resistors must be kept near the device to minimize the trace length connected to the FB pin. The connections from the FB voltage divider resistors and the GOSNS pin to the remote location must be a pair of PCB traces with Kelvin sensing across a bypass capacitor of 0.1μF or higher. To maintain stable output voltage and minimize the ripple, the pair of remote sensing lines must stay away from any noise sources such as inductor and SW nodes, or high frequency clock lines. TI recommends to shield the pair of remote sensing lines with ground planes above and below.

Single-ended V_OUT sensing can also be used for local sensing. For this configuration connect the higher FB resistor R_{FB_T} to a high-frequency local bypass capacitor of 0.1μF or higher, and short GOSNS to AGND.

The recommended GOSNS operating range (relative to the AGND pin) is –100mV to +100mV.
