PIN FUNCTION DESCRIPTIONS
Pin No.
Mnemonic
Function
1–5
VID3, VID2,
Voltage Identification DAC Inputs. These pins are pulled up to an internal reference,
VID1, VID0,
providing a logic one if left open. The DAC output programs the FB regulation voltage from
VID25
1.05 V to 1.825 V.
6
PWRGD
Open drain output that signals when the output voltage is in the proper operating range.
7
REF
3.0 V Reference Output.
8
SD
Regulator Shutdown. Pulling this pin high turns off both MOSFETs of the switching
regulator. SD has no effect on the linear regulator controller.
9
FB
Feedback Input. Error amplifier input for remote sensing of the output voltage.
10
CS–
Current Sense Negative Node. Negative input for the current comparator.
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
CT
External capacitor connected from CT to ground sets the OFF-Time of the device.
13
COMP
Error Amplifier Output and Compensation Point. The voltage at this output programs the
output current control level between CS+ and CS–.
14
LRDRV
Gate Drive for the 1.8 V linear regulator N-channel MOSFET.
15
LRFB
Feedback Connections for the 1.8 V linear regulator controller.
16
VCC
Supply Voltage for the ADP3170.
17
DRVL
Low-Side MOSFET Drive. Gate drive for the synchronous rectifier N-channel MOSFET.
The voltage at DRVL swings from GND to VCC.
18
DRVH
High-Side MOSFET Drive. Gate drive for the buck switch N-channel MOSFET. The voltage
at DRVH swings from GND to VCC.
19
PGND
Power Ground. PGND should have a low impedance path to the source of the synchronous
MOSFET.
20
GND
Small-Signal Ground. This ground reference can be used in conjunction with FB to provide
remote sensing of the output voltage at the CPU pins.
