DATASHEET  
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 VIDTM technology 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  
IN  
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.
