To disable the load-line, short FBDC2 to the positive remote-sense point.
FBDC1 is high impedance in shutdown.
SMPS1 Remote Ground-Sense Input. Normally connected to GND directly at the load. GNDS1 internally
connects to a transconductance amplifier that fine tunes the output voltage compensating for voltage
drops from the regulator ground to the load ground.
GNDS1 is the remote ground-sense input in combined-mode operation.
Exposed Pad. Connect the exposed backside pad to GND1 and GND2.
