Microproces s or CORE Voltage Regulator

Multi-Phas e Buck PWM Controller

Features

• Multi-Phase Power Conversion

The ISL6552 multi-phase PWM control IC together with its

companion gate drivers, the HIP6601, HIP6602 or HIP6603

and external Intersil MOSFETs provides a precision voltage

regulation system for advanced microprocessors.

• Precision Channel Current Sharing

- Loss Less Current Sampling - Uses r

DS(ON)

• Precision CORE Voltage Regulation

Multi-phase 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 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 phase 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.

- ±1% System Accuracy Over Temperature

• Microprocessor Voltage Identification Input

- 5-Bit VID Input

- 1.05V to 1.825V 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

• QFN Package:

Outstanding features of this controller IC include

- Compliant to JEDEC PUB95 MO-220

programmable VID codes from the microprocessor that

range from 1.05V to 1.825V 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.

QFN - Quad Flat No Leads - Package Outline

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

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 RMS output current to 41% of the

programmed over-current trip value. These features provide

monitoring and protection for the microprocessor and power

system.
