PIN DESCRIPTION
Analog Voltage Input - Used with VOUT to program the regulator output voltage. The typical input impedance of VOUT_SET
with respect to VSEN_REM- is 500kΩ. The voltage input typ. is 0.6V.
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.
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. The voltage output range is 0V to 5V.
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.
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 126µA typ.
The ISET and ISHARE pins are used for current sharing purposes with multiple ISL8200AMMREP modules. In the single
module configuration, this pin can be tied to the ISHARE pin. In multi-phase operation, if noise is a concern, add an additional
10pF capacitor to the ISET line.
