HIP6301V, HIP6302V

Data Sheet  
March 2002  
FN9034.1  
Current sensing is accomplished by reading the voltage  
Microprocessor CORE Voltage Regulator  
Multi-Phase Buck PWM Controller  
developed across the lower MOSFETs during their  
conduction intervals. Current sensing provides the needed  
signals for precision droop, channel-current balancing, load  
sharing, and over-current protection. This saves cost by  
taking advantage of the power device’s parasitic on  
resistance.  
The HIP6301V and HIP6302V control microprocessor core  
voltage regulation by driving up to four synchronous-rectified  
buck channels in parallel. Multi-phase buck converter  
architecture uses interleaved timing to multiply ripple  
frequency and reduce input and output ripple currents.  
Lower ripple results in fewer components, lower component  
cost, reduced power dissipation, and smaller implementation  
area. The HIP6301V is a versatile two to four phase  
controller and the HIP6302V is a cost-saving dedicated  
two-phase controller.  
Features  
• Multi-Phase Power Conversion  
• Precision CORE Voltage Regulation  
- ±0.8% System Accuracy Over Temperature  
The HIP6301V and HIP6302V are exact pin compatible  
replacements for their predecessor parts, the HIP6301 and  
HIP6302. They are the first controllers to incorporate  
Dynamic VID™ technology to manage the output voltage  
and current during on-the-fly DAC changes. Using Dynamic  
VID, the HIP6301V and HIP6302V detect changes in the VID  
code and gradually change the reference in 25mV  
increments until reaching the new value. By gradually  
changing the reference setting, inrush current and the  
accompanying voltage swings remain negligibly small.  
• Microprocessor Voltage Identification Input  
- Dynamic-VID Technology  
- 5-Bit VID Decoder  
• Precision Channel-Current Balance  
• Overcurrent Protection  
• Lossless Current Sensing  
• Programmable “Droop” Voltage  
• Fast Transient Response  
Intersil offers a wide range of MOSFET drivers to form highly  
integrated solutions for high-current, high slew-rate  
applications. The HIP6301V and HIP6302V regulate output  
voltage, balance load currents and provide protective  
functions for two to four synchronous-rectified buck  
converter channels. These parts feature an integrated high-  
bandwidth error amplifier for fast, precise regulation and a  
five-bit DAC for the digital interface to program the 0.8%  
accuracy. A window comparator toggles PGOOD if the  
output voltage moves out of range and acts to protect the  
load in case of over voltage.  
• Selection of 2, 3, or 4 Phase Operation  
• High Ripple Frequency (100kHz to 6MHz)
