Microprocessor CORE Voltage Regulator

Multi-Phase Buck PWM Controller

Features

• Precision CORE Voltage Regulation

- ±0.5% System Accuracy Over Temperature

The HIP6311A Multi-Phase Buck PWM control IC together

with HIP6601A, HIP6602A or HIP6603A companion gate

drivers form a precision voltage regulation system for

advanced microprocessors. The HIP6311A controls

microprocessor core voltage regulation by driving 2 to 4

synchronous-rectified buck channels in parallel. The multi-

phase buck topology takes advantage of interleaving phases

to increase ripple frequency and reduce input and output

ripple currents. Resulting in fewer components, reduced

component ratings, lower power dissipation, and smaller

implementation area.

• Microprocessor Voltage Identification Input

- 5-Bit VID Input

- 1.100V to 1.850V in 25mV Steps

- Programmable Droop Voltage

• R

Current Sensing

- Accurate Channel Current Balancing

- Loss less Current Sampling

- Low-Cost Implementation

• Fast Transient Response

• Digital Soft Start

The HIP6311A control IC features a 5 bit digital-to-analog

converter (DAC) that adjusts the core output voltage from

1.100V to 1.850V with an unsurpassed system accuracy of

±0.5% over temperature. The HIP6311A uses a lossless

current sensing approach in which the voltage developed

across the on-resistance of the lower MOSFETs during

conduction is sampled. Current sensing provides the

required signals for precision droop, channel-current

balancing, load sharing, and over-current protection.

• Over Current Protection

• Selection of 2, 3, or 4 Phase Operation

• 50kHz to 1.5MHz Switching Frequency

• Pb-free available

Applications

Another feature of this control IC is the PGOOD monitor

which is held low until the core voltage increases to within

8% of the programmed voltage. An over-voltage condition is

detected when the output voltage exceeds 115% of the

programmed VID. This results in the converter shutting down

and PGOOD being pulled low. During an under-voltage

condition (output voltage 10% below the programmed VID),

PGOOD transitions low, but the converter continues to

operate.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
