PIN FUNCTION DESCRIPTIONS
Pin Mnemonic
Function
1–4, VID3 –VID0, Voltage Identication DAC Inputs.
5
VID25
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 1.05 V to 1.825 V.
6
COMP
Error Amplier Output and Compensation
Point. The voltage at this output programs
the output current control level between
CS+ and CS–.
7
FB
Feedback Input. Error amplier input for
remote sensing of the output voltage.
8
CT
External capacitor CT connection to ground
sets the frequency of the device.
9
GND
Ground. All internal signals of the ADP3162
are referenced to this ground.
10
PWRGD
Open drain output that signals when the out-
put voltage is in the proper operating range.
11
CS+
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–.
12
PWM2
Logic-level output for the Phase 2 driver.
13
PWM1
Logic-level output for the Phase 1 driver.
14
CS–
Current Sense Negative Node. Negative
input for the current comparator.
15
REF
3.0 V Reference Output.
16
VCC
Supply Voltage for the ADP3162.

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 ADP3162 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.
WARNING!
