LTC1706-81
PIN FUNCTIONS
VID0 (Pin 1): LSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID0 adds 50mV
(VID4 = LOW) or 100mV (VID4 = HIGH) to the output
sense voltage.
VID1 (Pin 2): 3rd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID1 adds 100mV
(VID4 = LOW) or 200mV (VID4 = HIGH) to the output
sense voltage.
VID2 (Pin 3): 2nd MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID2 adds 200mV
(VID4 = LOW) or 400mV (VID4 = HIGH) to the output
sense voltage.
VID3 (Pin 4): MSB Programming Input. Low = GND,
High = VCC or Float. Grounding VID3 adds 400mV
(VID4 = LOW) or 800mV (VID4 = HIGH) 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 or, when used with
the LTC1629 and LTC1929 to VDIFFOUT.
VID4 (Pin 7): High-Low Output Range Programming
Input. VID4 = Low puts the output voltage in the lower
range of 1.3V to 2.05V in 50mV steps. VID4 = HIGH puts
the output voltage in the upper range of 2.1V to 3.5V in
100mV steps.
NC (Pin 8): No Connect.
GND (Pin 9): Ground. Connect to regulator signal ground.
FB (Pin 10): Feedback Input. Connect to the 0.8V feedback
pin of a compatible regulator or the EAIN pin of the
LTC1629 and LTC1929.
