Multi-Phase Buck PWM Controller
The ISL6553 multi-phase PWM control IC together with its
companion gate drivers, the HIP6601, HIP6602 or HIP6603

microprocessors. Multi-phase 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
converters, 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 two phase converter operating at
350kHz will have a ripple frequency of 700kHz. Moreover,
greater converter 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
range from 1.05V to 1.825V with a system accuracy of ± 1%.

Pull up currents on these VID pins eliminates the need for
external pull up resistors. In addition “droop” compensation,
used to reduce the overshoot or undershoot of the CORE
voltage, is easily programmed with a single resistor.
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

programmed level. Over-current protection reduces the
regulator RMS output current to 41% of the programmed
over-current trip value. These features provide monitoring
and protection for the microprocessor and power system.
NOTE: Intersil Pb-free products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish, which
is 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-020B.
