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. Multiphase
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 a smaller
implementation area. The HIP6301V is a versatile 2- to
4-phase controller and the HIP6302V is a cost-saving
dedicated 2-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, in-rush 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 5-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 overcurrent protection. This saves cost by
taking advantage of the power device’s parasitic on
resistance.
