The device integrates a remote sense amplifier across the VOS/FB and GOS 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 FB voltage divider resistors (if used) 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 GOS 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 is often used for local sensing. For this configuration, connect the higher FB resistor, R_{FB_HS}, to a high-frequency local bypass capacitor of 0.1μF or higher, and short GOS to AGND.

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