Microprocessor CORE Voltage Regulator

Multi-Phase Buck PWM Controller

Features

• Multi-Phase Power Conversion

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.
