Microprocessor CORE Voltage Regulator

Multi-Phase Buck PWM Controller

Features

• Multi-Phase Power Conversion

The HIP6311 multi-phase PWM control IC together with its

companion gate drivers, the HIP6601, HIP6602 or HIP6603

and internal MOSFETs provides a precision voltage

regulation system for advanced microprocessors.

Multiphase power conversion is a marked departure from

earlier single phase converter configurations previously

employed to satisfy the ever increasing current demands of

modern microprocessors. Multi-phase convertors, by

distributing the power and load current results in smaller and

lower cost transistors with fewer input and output capacitors.

These reductions accrue from the higher effective

conversion frequency with higher frequency ripple current

due to the phase interleaving process of this topology. For

example, a three phase convertor operating at 350kHz will

have a ripple frequency of 1.05MHz. Moreover, greater

convertor bandwidth of this design results in faster response

to load transients.

• Precision Channel Current Sharing

- Loss Less Current Sampling - Uses r

DS(ON)

• Precision CORE Voltage Regulation

- ±0.8% System Accuracy Over Temperature

• Microprocessor Voltage Identification Input

- 5-Bit VID Input

- 1.100V to 1.850V in 25mV Steps

- Programmable “Droop” Voltage

• Fast Transient Recovery Time

• Over Current Protection

• Automatic Selection of 2, 3, or 4 Phase Operation

• High Ripple Frequency, (Channel Frequency) Times

Number Channels . . . . . . . . . . . . . . . . . .100kHz to 6MHz

• Pb-Free Available (RoHS Compliant)

Outstanding features of this controller IC include

programmable VID codes from the microprocessor that

range from 1.100V to 1.850V with a system accuracy of

±0.8%. Pull up currents on these VID pins eliminates the

need for external pull up resistors. In addition “droop”

compensation, used to reduce the overshoot or undershoot

of the CORE voltage, is easily programmed with a single

resistor.

Evaluation Platform

Another feature of this controller IC is the PGOOD monitor

circuit which is held low until the CORE voltage increases,

during its Soft-Start sequence, to within 10% of the

programmed voltage. Over-voltage, 15% above

programmed CORE voltage, results in the converter shutting

down and turning the lower MOSFETs ON to clamp and

protect the microprocessor. Under voltage is also detected

and results in PGOOD low if the CORE voltage falls 10%

below the programmed level. Over-current protection

reduces the regulator current to less than 25% of the

programmed trip value. These features provide monitoring

and protection for the microprocessor and power system.

*Add “-T” suffix to part number for tape and reel packaging.

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

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

plate termination finish, which are RoHS compliant and 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-020.
