Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller  
The ISL6552 multi-phase PWM control IC together with its  
companion gate drivers, the HIP6601, HIP6602 or HIP6603  
Features  
• Multi-Phase Power Conversion  
and external 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 three phase converter operating at 350kHz will  
have a ripple frequency of 1.05MHz. Moreover, greater  
converter bandwidth of this design results in faster response  
to load transients.  
• Precision Channel Current Sharing  
- Loss Less Current Sampling - Uses r  
• Precision CORE Voltage Regulation  
DS(ON)  
- 1% System Accuracy Over Temperature  
• Microprocessor Voltage Identification Input  
- 5-Bit VID Input  
- 1.05V to 1.825V in 25mV Steps  
- Programmable “Droop” Voltage  
• Fast Transient Recovery Time  
• Over Current Protection  
• Automatic Selection of 2, 3, or 4 Phase Operation  
• High Ripple Frequency (Channel Frequency) Times  
Number Channels . . . . . . . . . . . . . . . . . .100kHz to 6MHz  
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.  
• QFN Package:  
- Compliant to JEDEC PUB95 MO-220  
QFN - Quad Flat No Leads - Package Outline  
- Near Chip Scale Package footprint, which improves  
PCB efficiency and has a thinner profile  
• Pb-free available  
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  
Ordering Information  
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.
