Data Sheet

File Number 4765.1  
Microprocessor CORE Voltage Regulator  
Multi-Phase Buck PWM Controller  
Features  
• Multi-Phase Power Conversion  
The HIP6301 multi-phase PWM control IC together with its  
companion gate drivers, the HIP6601, HIP6602 or HIP6603  
and internal MOSFETs provides a precision voltage  
regulation system for advanced microprocessors.  
Multiphase 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 convertors, 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 convertor operating at 350kHz will  
have a ripple frequency of 1.05MHz. Moreover, greater  
convertor bandwidth of this design results in faster response  
to load transients.  
• Precision Channel Current Sharing  
- Loss Less Current Sampling - Uses r  
DS(ON)  
• Precision CORE Voltage Regulation  
- ±1% System Accuracy Over Temperature  
• Microprocessor Voltage Identification Input  
- 5-Bit VID Input  
- 1.100V to 1.850V 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 1.100V to 1.850V 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 current to less than 25% of the programmed trip  
value. These features provide monitoring and protection for  
the microprocessor and power system.
