PIN FUNCTIONS COMP (F6):
Current Control Threshold and Error Amplifier
DIFFP (F8):
Input to the Remote Sense Amplifier. This Compensation Point. The current comparator threshold pin connects to the output remote sense point. Connect increases with this control voltage. Tie all COMP pins to GND when not used. together in parallel operation.
DIFFOUT (G8):
Output of the Remote Sense Amplifier.
DIFFN (F7):
Input to the Remote Sense Amplifier. This This pin connects to the VOUT_LCL pin for remote sense pin connects to the ground remote sense point. Connect applications. Otherwise float when not used. to GND when not used.
