Functional Pin Description
VID3 (Pin 1), VID2 (Pin 2), VID1 (Pin 3) and VID0
(Pin 4)
Voltage Identification inputs from microprocessor. These pins
respond to TTL and 3.3V logic signals. The HIP6304 decodes
VID bits to establish the output voltage. See Table 1.
EN (Pin 5)
Enable pin normal operation is with input open or high. A low
input disables the regulator and three states the PWM outputs.
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)
Channel frequency, F
SW
, select and disable. A resistor from
this pin to ground sets the switching frequency of the
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.
ISEN2 (Pin 11) and ISEN1 (Pin 14)
Current sense inputs from the individual converter channel’s
phase nodes.
PWM2 (Pin 12) and PWM1 (Pin 13)
PWM outputs for each driven channel in use. Connect these
pins to the PWM input of a HIP6601/2/3 driver.
PGOOD (Pin 15)
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
CC
(Pin 16)
Bias supply. Connect this pin to a 5V supply.
