Microprocessor CORE Voltage Regulator

Precision Multi-Phase BUCK PWM

Controller for Mobile Applications

Features

• Multi-Phase Power Conversion

• Active Channel Current Balancing

• Lossless current sense scheme

The ISL6219A provides core-voltage regulation by driving up

to three interleaved synchronous-rectified buck-converter

channels in parallel. Intersil multi-phase controllers together

with ISL6207 gate drivers form the basis for the most reliable

power-supply solutions available to power the latest

industry-leading microprocessors. Multi-phase buck-converter

architecture uses interleaved timing to multiply ripple

frequency and reduce input and output ripple currents. Lower

ripple results in lower total component cost, reduced

dissipation, and smaller implementation area. Pre-configured

for 3-phase operation, the ISL6219A offers the flexibility of

2-phase operation. Simply connect the unused PWM pin to

+5V. The channel switching frequency is adjustable in the

range of 100kHz to 1.5MHz giving the designer the ultimate

flexibility in managing the balance between high-speed

response and good thermal management.

- Uses MOSFET’s r

DS(ON)

- Optional current sense method for higher precision

• Precision CORE Voltage Regulation

- ±0.8% System Accuracy Over Temperature

• Microprocessor Voltage Identification Input

- Dynamic VID technology

- 5-Bit VID Input

- 1.100V to 1.850V in 25mV Steps

• Programmable Droop Voltage

• Fast Transient Recovery Time

• Overvoltage, Undervoltage and Overcurrent Protection

• Power-Good Output

• 2 or 3 Phase Operation

New features on the ISL6219A include Dynamic-VID™

technology allowing seamless on-the-fly VID changes with

no need for any additional external components. When the

ISL6219A receives a new VID code, it incrementally steps

the output voltage to the new level. Dynamic VID™ changes

are fast and reliable with no output voltage overshoot or

undershoot.

• User selectable Switching Frequency of 100kHz to 1.5MHz

- 200kHz - 4.5MHz Effective Ripple Frequency

balance and dynamic voltage positioning. Channel current

tailored to any application with no need of additional parts.

FS/EN

An integrated DAC decodes the 5-bit logic signal present at

VID0-VID4 and provides an accurate reference for precision

voltage regulation. The high-bandwidth error amplifier and

accurate voltage reference all work together to provide

better than 0.8% total system accuracy, and to enable the

fastest transient response available. A window comparator

toggles PGOOD if the output voltage moves out of range

and acts to protect the load in case of overvoltage.
