Two-Phase Multiphase Buck PWM
Controller with Integrated MOSFET Drivers
The ISL8101 two-phase PWM control IC provides a
precision voltage regulation system for advanced loads up to
60A to 80A. Multiphase power conversion is a marked
departure from single phase converter configurations
employed to satisfy the increasing current demands of
modern microprocessors and other electronic circuits. By
distributing the power and load current, implementation of
multiphase converters utilize 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.
Outstanding features of this controller IC include programmable
VID codes compatible with Intel VRM9, VRM10, as well as
AMD’s Hammer microprocessors, along with a system
regulation accuracy of ± 1%. The ISL8101, though, does not
intrinsically allow for load-line regulation (no droop).
Important features of this controller IC include a set of
sophisticated overvoltage and overcurrent protection.
Overvoltage results in the converter turning the lower
MOSFETs ON to clamp the rising output voltage and protect
the microprocessor. Like other Intersil multiphase
controllers, the ISL8101 uses cost and space-saving
r DS(ON) sensing for channel current balance and
overcurrent protection. Channel current balancing is
automatic and accurate with the integrated current-balance
control system. Overcurrent protection can be tailored to any
application with no need for additional parts. These features
provide intelligent protection for modern power systems.
