HIP6301V, HIP6302V

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.
