Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
The HIP6301V and HIP6302V control microprocessor
CORE voltage regulation by driving up to four
synchronous-rectified buck channels in parallel. Multiphase
buck converter architecture uses interleaved timing to
multiply ripple frequency and reduce input and output ripple
currents. Lower ripple results in fewer components, lower
component cost, reduced power dissipation, and a smaller
implementation area. The HIP6301V is a versatile 2- to
4-phase controller and the HIP6302V is a cost-saving
dedicated 2-phase controller.
The HIP6301V and HIP6302V are exact pin compatible
replacements for their predecessor parts, the HIP6301 and
HIP6302. They are the first controllers to incorporate
Dynamic VID™ technology to manage the output voltage
and current during on-the-fly DAC changes. Using Dynamic
VID, the HIP6301V and HIP6302V detect changes in the
VID code, and gradually change the reference in 25mV
increments until reaching the new value. By gradually
changing the reference setting, in-rush current and the
accompanying voltage swings remain negligibly small.
Intersil offers a wide range of MOSFET drivers to form highly
integrated solutions for high-current, high slew-rate
applications. The HIP6301V and HIP6302V regulate output
voltage, balance load currents and provide protective
functions for two to four synchronous-rectified buck
converter channels. These parts feature an integrated
high-bandwidth error amplifier for fast, precise regulation
and a 5-bit DAC for the digital interface to program the 0.8%
accuracy. A window comparator toggles PGOOD if the
output voltage moves out of range, and acts to protect the
load in case of over voltage.

Current sensing is accomplished by reading the voltage
developed across the lower MOSFETs during their
conduction intervals. Current sensing provides the needed
signals for precision droop, channel-current balancing, load
sharing, and overcurrent protection. This saves cost by
taking advantage of the power device’s parasitic on
resistance.
*Add “-T” suffix for tape and reel. Please refer to TB347 for details on
reel specifications.
NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach materials
and 100% matte tin plate PLUS ANNEAL - e3 termination finish, which
is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at Pb-
free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.

VID4, VID3, VID2, VID1 and VID0
(Pins 1 thru 5 - Both Parts)
Voltage Identification inputs. The HIP6301V and HIP6302V
decode the VID bits to establish the reference voltage (see
Table 1). Each pin has an internal 20µA pull-up current source
to 2.5V making the parts compatible with CMOS and TTL
logic from 5V down to 2.5V. When a VID change is detected,
the reference voltage slowly ramps up or down to the new
value in 25mV steps. VID input levels above 2.9V may
produce an reference-voltage offset inaccuracy.
COMP (Pin 6 - Both Parts)
Output of the internal error amplifier. Connect this pin to the
external feedback and compensation network.
FB (Pin 7 - Both Parts)
Inverting input of the internal error amplifier.
FS/DIS (Pin 8 - Both Parts)
Channel frequency, FSW, 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 - Both Parts)
Bias and reference ground. All signals are referenced to this
pin.
VSEN (Pin 10 - Both Parts)
Power-good monitor input. Connect to the microprocessor CORE
voltage.
PWM1 (Pin 15 - HIP6301V, Pin 13 - HIP6302V),
PWM2 (Pin 14 - HIP6301V, Pin 12 - HIP6302V),
PWM3 (Pin 11 - HIP6301V only) and PWM4
(Pin 18 - HIP6301V only)
PWM outputs for each channel. Connect these pins to the
PWM input of the external MOSFET driver. For HIP6301V
systems using 3 channels, connect PWM4 high. For two
channel systems, connect PWM3 and PWM4 high.
ISEN1 (Pin 16 - HIP6301V, Pin 14 - HIP6302V),
ISEN2 (Pin 13 - HIP6301V, Pin 11 - HIP6302V),
ISEN3 (Pin 12 - HIP6301V only) and ISEN4
(Pin 17 - HIP6301V only)
Current sense inputs from the individual converter channel’s
phase nodes. Unused sense lines MUST be left open.
PGOOD (Pin 19 - HIP6301V, Pin 15 - HIP6302V)
Power-good. This pin is an open-drain logic signal that
indicates when the microprocessor CORE voltage (VSEN
pin) is within specified limits and soft-start has timed out.
VCC (Pin 20 - HIP6301V, Pin 16 - HIP6302V)
Bias supply. Connect this pin to a 5V supply.
