Functional Pin Description
VID4 (Pin 1), VID3 (Pin 2), VID2 (Pin 3), VID1 (Pin 4)
and VID0 (Pin 5)
Voltage Identification inputs from microprocessor. These pins
respond to TTL and 3.3V logic signals. The HIP6311 decodes
VID bits to establish the output voltage. See Table 1.
COMP (Pin 6)
Output of the internal error amplifier. Connect this pin to the
external feedback and compensation network.
FB (Pin 7)
Inverting input of the internal error amplifier.
FS/DIS (Pin 8)

converter. Pulling this pin to ground disables the converter
and three states the PWM outputs. See Figure 10.
GND (Pin 9)
Bias and reference ground. All signals are referenced to this
pin.
VSEN (Pin 10)
Power good monitor input. Connect to the microprocessor-
CORE voltage.
PWM1 (Pin 15), PWM2 (Pin 14), PWM3 (Pin 11) and
PWM4 (Pin 18)
PWM outputs for each driven channel in use. Connect these
pins to the PWM input of a HIP6601/2/3 driver. For systems
which use 3 channels, connect PWM4 high. Two channel
systems connect PWM3 and PWM4 high.
ISEN1 (Pin 16), ISEN2 (Pin 13), ISEN3 (Pin 12) and
ISEN4 (Pin 17)
Current sense inputs from the individual converter channel’s
phase nodes. Unused sense lines MUST be left open.
PGOOD (Pin 19)
Power good. This pin provides a logic-high signal when the
microprocessor CORE voltage (VSEN pin) is within specified
limits and Soft-Start has timed out.
V
Bias supply. Connect this pin to a 5V supply.
