Voltage output signal proportional to total current drawn from the VDDNB regulator. Used when load
line operation (“droop”) is desired.
Voltage error amplifier inverting input for the V
Output of the voltage error amplifier for the V
Parallel Voltage ID DAC Input 0. Not used in SVI mode.
Parallel Voltage ID DAC Input 1. Also used for PVI or SVI mode selection.
System power supplies status input. Used in SVI mode only.
High = Run, Low = Standby/Reset.
Parallel Voltage ID DAC Input 1. Also used in SVI mode.
Parallel Voltage ID DAC Input 1. Also used in SVI mode.
Open drain output. High indicates that the active output(s) are within specification.
Bidirectional Gate Drive Enable to the gate driver for the V
Bidirectional Gate Drive Enable to gate drivers for the V
PWM output to the V
PWM output #4. See Table: “Pin Connections vs. Phase Count”
PWM output #3. See Table: “Pin Connections vs. Phase Count”
PWM output #2. See Table: “Pin Connections vs. Phase Count”
PWM output #1. See Table: “Pin Connections vs. Phase Count”
High-current power supply return via metal pad (flag) underneath package. The package flag should
be tied directly to Pin 2.
