DATASHEET  
ISL6219A  
FN9093  
Rev.1.00  
Mar 20, 2007  
Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM  
Controller for Mobile Applications  
The ISL6219A provides core-voltage regulation by driving up  
to three interleaved synchronous-rectified buck-converter  
Features  
• Multi-Phase Power Conversion  
• Active Channel Current Balancing  
• Lossless current sense scheme  
- Uses MOSFET’s r  
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.  
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  
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.  
• 2 or 3 Phase Operation  
• User selectable Switching Frequency of 100kHz to 1.5MHz  
- 200kHz - 4.5MHz Effective Ripple Frequency

(28 LD QSOP)  
TOP VIEW  
Like other Intersil multiphase controllers, the ISL6219A uses  
cost and space-saving r  
sensing for channel current  
DS(ON)  
balance and dynamic voltage positioning. Channel current  
balancing is automatic and accurate with the integrated  
current-balance control system. Overcurrent protection can be  
tailored to any application with no need of additional parts.

PGOOD  
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.
