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 600kΩ. The typical input voltage is 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 start-up. The output voltage range is 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. The output current range is 15μA to 108μA typical.
