ISL6553
Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
The ISL6553 multi-phase PWM control IC together with its
companion gate drivers, the HIP6601, HIP6602 or HIP6603
and Intersil MOSFETs provides a precision voltage
regulation system for advanced 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
in PGOOD low if the CORE voltage falls 10% below the
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.
