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
ADP3171 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.

Ground Reference. GND should have a low impedance path to the source of the synchronous MOSFET.
Power Good Indicator. Open-drain output that signals when the output voltage is in the proper operating range.
Feedback connections for the fixed output voltage linear regulator controllers.
Gate drives for the respective linear regulator N-channel MOSFETs.
Feedback Input. Error amplifier input for remote sensing of the output voltage.
Current Sense Negative Node. Negative input for the current comparator.
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–.
Timing Capacitor. An external capacitor connected from CT to ground sets the off time of the device.
Error Amplifier Output and Compensation Point. The voltage at this output programs the output current control
level between CS+ and CS–.
Supply Voltage for the ADP3171.
Low-Side MOSFET Drive. Gate drive for the synchronous rectifier N-channel MOSFET. The voltage at DRVL
swings from GND to VCC.
High-Side MOSFET Drive. Gate drive for the buck switch N-channel MOSFET. The voltage at DRVH swings
from GND to VCC.
