Voltag

The ISL6553 multi-phase PWM control IC together with its

companion gate drivers, the HIP6601, HIP6602 or HIP6603

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.

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.

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.
