5 V supply pin for the NCP5393. The V
pin and GND (preferably returned to the package flag).
Small-signal power supply return. This pin should be tied directly to the package flag (exposed pad).
Output of the voltage error amplifier for the V
Voltage error amplifier inverting input for the V
Voltage output signal proportional to total current drawn from the V
operation (“droop”) is desired.
Non-inverting input to the differential remote sense amplifier for the V
Inverting input to the differential remote sense amplifier for the V
Input for offset voltage to be added to the V
offset.
Output of the differential remote sense amplifier for the V
When pulled low, this pin causes the levels on the SVC (VID3) and SVD (VID2) pins to be decoded
as a two-bit DAC code, which controls the V
UVLO monitor input for the 12 V power rail.
Power Saving Control. Low = single phase operation, High = normal operation. This pin is not used in
SVI mode.

ally used to develop an appropriate voltage on ILIM.
5 V supply pin. Tie this pin to VCCA (Pin 1).
Non-inverting input to the current sense amplifier for the VDDNB regulator
Inverting input to the current sense amplifier for the VDDNB regulator
Parallel Voltage ID DAC Input 4. Not used in SVI mode.
Parallel Voltage ID DAC Input 5. Not used in SVI mode.
A resistance from this pin to ground programs the V
supplies a trimmed output voltage of 2 V.
Output of the differential remote sense amplifier for the VDDNB regulator.
Input for offset voltage to be added to the VDDNB DAC's output voltage. Ground this pin for zero
VDDNB offset.
