HIP6301V, HIP6302V

Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller

DATASHEET

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.
