DATASHEET  
ISL6569A  
Multi-Phase PWM Controller  
FN9092  
Rev 2.00  
Dec 29, 2004  
The ISL6569A provides core-voltage regulation by driving  
two 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 Phase Operation  
• Active Channel Current Balancing  
• Precision r  
DS(ON)  
- Lossless  
Current Sharing  
- Low Cost  
The ISL6569A uses cost and space-saving r  
sensing  
DS(ON)  
• Input Voltage: 12V or 5V Bias  
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 reference and amplifiers are trimmed to ensure  
a system accuracy of ±0.5% over temperature.  
• Precision CORE Voltage Regulation  
- ±0.5% System Accuracy Over Temperature  
- Differential Remote Output Voltage Sensing  
- Programmable Reference Offset  
• Microprocessor Voltage Identification Input  
- 5-Bit VID Input  
- 0.800V to 1.550V in 25mV Steps  
- Dynamic VIDTM 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 2MHz)  
• 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  
Superior over-voltage protection is achieved by gating on the  
lower MOSFET of all phases to crowbar the output voltage.  
• Pb-Free Available (RoHS Compliant)  
An optional second crowbar on V , formed with an external  
IN  
Applications  
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.

• Low Output Voltage, High Current DC-DC Converters  
• Voltage Regulator Modules
