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.

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.
Error Amplifier Output and Compensation
Point. The voltage at this output programs
the output current control level between
CS+ and CS–.
Feedback Input. Error amplifier input for
remote sensing of the output voltage.
External Capacitor CT Connection to
ground sets the frequency of the device.
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–.
Logic-Level Output for Phase 2 Driver
Logic-Level Output for Phase 1 Driver
Current Sense Negative Node. Negative
input for the current comparator.
3.0 V Reference Output
Supply Voltage for the ADP3160/ADP3167.
