1–5 VID4–
VID0
Voltage Identification DAC Inputs.
These pins are pulled up to an internal
reference, providing a Logic 1 if left open.
The DAC output programs the FB regula-
tion voltage from 1.1 V to 1.85 V. Leaving
all five DAC inputs open results in the
ADP3160/ADP3167 going into a “No
CPU” mode, shutting off its PWM outputs.

6
COMP
Error Amplifier Output and Compensation
Point. The voltage at this output programs
the output current control level between
CS+ and CS–.
*This is a stress rating only; operation beyond these limits can cause the device to
be permanently damaged. Unless otherwise specified, all voltages are referenced
to GND.
7
FB
Feedback Input. Error amplifier input for
remote sensing of the output voltage.
8
CT
External Capacitor CT Connection to
ground sets the frequency of the device.

GND
PWRGD
CS+
Ground. All internal signals of the ADP3160/
ADP3167 are referenced to this ground.
Open-Drain Output that signals when the
output voltage is in the proper operating range.
Current Sense Positive Node. Positive input
for the current comparator. The output
current is sensed as a voltage at this pin with
respect to CS–.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADP3160/ADP3167 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
