Microprocessor CORE Voltage Regulator

Multi-Phase Buck PWM Controller

Features

• AMD Athlon Compatible

The HIP6303 multi-phase PWM control IC together with its

companion gate drivers, the HIP6601, HIP6602 or HIP6603

and Intersil MOSFETs provides a precision voltage

regulation system for advanced microprocessors.

• Multi-Phase Power Conversion

• Precision Channel Current Sharing

- Loss Less Current Sampling - Uses r

DS(ON)

Multiphase power conversion is a marked departure from

earlier single channel converter conﬁgurations previously

employed to satisfy the ever increasing current demands of

modern microprocessors. Multi-phase converters, 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 channel converter operating at 350kHz will

have a ripple frequency of 1.05MHz. Moreover, greater

converter bandwidth of this design results in faster response

to load transients.

• Precision CORE Voltage Regulation

- ±1% System Accuracy Over Temperature

• Microprocessor Voltage Identiﬁcation Input

- 4-Bit VID Input

- 1.30V to 2.05V in 50mV Steps

- Programmable “Droop” Voltage

• Fast Transient Recovery Time

• Over Current Protection

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

• High Ripple Frequency, (Channel Frequency) Times

Outstanding features of this controller IC include

programmable VID codes from the microprocessor that

range from 1.30V to 2.05V with a system accuracy of ±1%.

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.

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.
