NUMBER PIN NAME
PIN DESCRIPTION
1
VOUT_SET Analog Voltage Input - Used with VOUT to program the regulator output voltage. The typical input
impedance of VSEN1+ with respect to VSEN1- is 500kΩ. Voltage input typ. 0.6V.
2
VSEN_REM- Analog Voltage Input - This pin is the negative input of standard unity gain operational amplifier for
differential remote sense for the regulator, and should connect to the negative rail of the
load/processor. This pin can be used for VOUT trimming by connecting a resistor from this pin to the
VOUT_SET pin.
3
ISFETDRV Digital Output - This pin is used to drive an optional NFET, which will connect ISHARE with the system
ISHARE bus upon completing a pre-bias startup. Voltage Output Range: 0V to 5V.
4, 15
PGND1
Normal Ground - All voltage levels are referenced to this pad.This pad provides a return path for the
low side MOSFET drives and internal power circuitries as well as all analog signals. PGND and PGND1
should be connected together with a ground plane.
5
ISET
Analog Current Output - This pin sources a 15µA offset current plus Channel 1’s average current. The
voltage (VISET) set by an external resistor (RISET) represents the average current level of the local
active module. For full-scale current, RISET should be ~10kΩ. Output current range: 15µA to 108µA
typ.
