ISL6559

Multi-Phase PWM Controller

FN9084

Rev 8.00

December 29, 2004

The ISL6559 provides core-voltage regulation by driving 2 to

4 interleaved synchronous-rectified buck-converter channels

in parallel. Interleaving the channel timing results in

increased ripple frequency which reduces input and output

ripple currents. The reduction in ripple results in lower

component cost, reduced dissipation, and a smaller

implementation area.

Features

• Multi-Phase Power Conversion

- 2, 3 or 4 Phase Operation

• Active Channel Current Balancing

• Precision r

DS(ON)

- Lossless

- Low Cost

Current Sharing

The ISL6559 uses cost and space-saving r

sensing

• Input Voltage: 12V or 5V Bias

• Precision CORE Voltage Regulation

- ±1% System Accuracy Over Temperature

- Differential Remote Output Voltage Sensing

- Programmable Reference Offset

• Microprocessor Voltage Identification Input

- 5-Bit VID Input

DS(ON)

for channel current balance, active voltage positioning, and

over-current protection. Output voltage is monitored by an

internal differential remote sense amplifier. A high-bandwidth

error amplifier drives the output voltage to match the

programmed 5-bit DAC reference voltage. The resulting

compensation signal guides the creation of pulse width

modulated (PWM) signals to control companion Intersil

MOSFET drivers. The OFS pin allows direct offset of the

DAC voltage from 0V to 50mV using a single external

resistor. The entire system is trimmed to ensure a system

accuracy of ±1% over temperature.

- 0.800V to 1.550V in 25mV Steps

- Dynamic VID Technology

• Programmable Droop Voltage

• Fast Transient Recovery Time

• Over Current Protection

Outstanding features of this controller IC include

Dynamic VID^TMtechnology allowing seamless on-the-fly VID

changing without the need of any external components.

Output voltage “droop” or active voltage positioning is

optional. When employed, it allows the reduction in size and

cost of the output capacitors required to support load

transients. A threshold-sensitive enable input allows the use

of an external resistor divider for start-up coordination with

Intersil MOSFET drivers or any other devices powered from

a separate supply.

• Digital Soft Start

• Threshold Sensitive Enable Input

• High Ripple Frequency (160kHz to 4MHz)

• QFN Package:

- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat

No Leads - Package Outline

- Near Chip Scale Package footprint, which improves PCB

efficiency and has a thinner profile

• Pb-Free Available (RoHS Compliant)

Applications

Superior over-voltage protection is achieved by gating on the

lower MOSFET of all phases to crowbar the output voltage.

• AMD Hammer Family Processor Voltage Regulator

• Low Output Voltage, High Current DC-DC Converters

• Voltage Regulator Modules

An optional second crowbar on V , formed with an external

MOSFET or SCR gated by the OVP pin, is triggered when

an over-voltage condition is detected. Under-voltage

conditions are detected, but PWM operation is not disrupted.

Over-current conditions cause a hiccup-mode response as

the controller repeatedly tries to restart. After a set number

of failed startup attempts, the controller latches off. A power

good logic signal indicates when the converter output is

between the UV and OV thresholds.
