Description
Microprocessor Core Voltage Regulator Multiphase Buck Pwm Controller
Manufacturer
Intersil Corporation
Datasheet
Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
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.
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.
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.
Current sensing is accomplished by reading the voltage
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.
