PI FU CTIO S
VID2 (Pin 1): 2nd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID2 adds 200mV to the
output sense voltage.
VID3 (Pin 2): 1st MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID3 adds 400mV to the
output sense voltage.
VCC (Pin 3): Power Supply Voltage. Range from 2.7V to
5.5V.
GND (Pin 4): Ground. Connect to regulator signal ground.
FB (Pin 5): Feedback Input. Connect to the 1.19V feedback
pin of a compatible regulator.
SENSE (Pin 6): Regulator Output Voltage. Connect di-
rectly to regulator output sense node.
VID0 (Pin 7): LSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID0 adds 50mV to the
output sense voltage.
VID1 (Pin 8): 3rd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID1 adds 100mV to the
output sense voltage.
