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  
Features  
• Multi-Phase Power Conversion  
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.  
• 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  
• High Ripple Frequency, (Channel Frequency) Times  
Number Channels . . . . . . . . . . . . . . . . . .100kHz to 3MHz  
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.  
• Pb-free available  
Related Literature  
• Technical Brief TB363 “Guidelines for Handling and  
Processing Moisture Sensitive Surface Mount Devices  
(SMDs)”  
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.
