PIN FUNCTIONS
VID0 (Pin 1): LSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID0 adds 12.5mV
to the output sense voltage.
VCC (Pin 5): Power Supply Voltage. Range from 2.7V to
5.5V.
SENSE (Pin 6): Regulator Output Voltage. Connect
directly to regulator output sense node.
VID1 (Pin 2): 4th MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID1 adds 25mV
to the output sense voltage.
VID4 (Pin 7): MSB Programming Input. Low = GND, High
= VCC or Float. Grounding VID4 adds 200mV to the output
sense voltage.
VID2 (Pin 3): 3rd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID2 adds 50mV
to the output sense voltage.
NC (Pin 8): No Connect.
GND (Pin 9): Ground. Connect to regulator signal ground.
FB(Pin10):FeedbackInput. Connecttothe0.6Vfeedback
VID3 (Pin 4): 2nd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID3 adds 100mV
to the output sense voltage.
