Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
The HIP6311 multi-phase PWM control IC together with its
companion gate drivers, the HIP6601, HIP6602 or HIP6603
and internal MOSFETs provides a precision voltage
regulation system for advanced microprocessors.
Multiphase power conversion is a marked departure from
earlier single phase converter configurations previously
employed to satisfy the ever increasing current demands of
modern microprocessors. Multi-phase convertors, by
distributing the power and load current results in smaller and
lower cost transistors with fewer input and output capacitors.
These reductions accrue from the higher effective
conversion frequency with higher frequency ripple current
due to the phase interleaving process of this topology. For
example, a three phase convertor operating at 350kHz will
have a ripple frequency of 1.05MHz. Moreover, greater
convertor bandwidth of this design results in faster response
to load transients.
Outstanding features of this controller IC include
programmable VID codes from the microprocessor that

Another feature of this controller IC is the PGOOD monitor
circuit which is held low until the CORE voltage increases,
during its Soft-Start sequence, to within 10% of the
programmed voltage. Over-voltage, 15% above
programmed CORE voltage, results in the converter shutting
down and turning the lower MOSFETs ON to clamp and
protect the microprocessor. Under voltage is also detected
and results in PGOOD low if the CORE voltage falls 10%
below the programmed level. Over-current protection

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are 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.
