Multi-Purpos e Precis ion Multi-Phas e PWM  
Controller With Optional Active Voltage  
Pos itioning  
Features  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
• Multi-Phase Power Conversion  
The ISL6558 is a multi-phase PWM controller, which in  
combination with the HIP6601B, HIP6602B, HIP6603B, or  
ISL6605 companion gate drivers form a complete solution  
for high-current, high slew-rate applications. The ISL6558  
regulates output voltage, balances load currents and  
provides protective functions for two to four synchronous  
rectified buck converter channels.  
- 2-, 3-, or 4-Phase Operation  
• Optional Output Voltage Droop  
• Precision Channel-Current Balance  
• Lossless Current Sensing  
• Precision Reference Voltage  
- 0.8V ± 1.5% Over -40°C - 85°C Range  
- 0.8V ± 1.0% Over 0°C - 70°C Range  
A novel approach to current sensing is used to reduce  
overall solution cost and improve efficiency. The voltage  
developed across the lower MOSFET during conduction is  
sampled and fed back to the controller. This lossless  
current-sensing approach enables the controller to maintain  
phase-current balance between the power channels, provide  
overcurrent protection, and permit droop compensation.  
• Fast Transient Response  
• Overcurrent and Overvoltage Protection  
• Digital Soft-start  
• Power Good Indication  
• High Ripple Frequency (80kHz to 1.5MHz)  
• QFN Package  
Optional output voltage “droop” or active voltage positioning  
is supported via the DROOP pin. Taking advantage of this  
feature reduces the size and cost of the output capacitors  
required to support a load transient.  
- Compliant to JEDEC PUB95 MO-220 QFN-Quad Flat  
No Leads-Product Outline  
- Near Chip-Scale Package Footprint; Improves PCB  
Efficiency and Thinner in Profile  
In the event of an overvoltage, the controller monitors and  
responds to reduce the risk of damage to load devices.  
Undervoltage conditions are indicated through a PGOOD  
transition. Overcurrent conditions cause the converter to  
shutdown limiting the exposure of load devices. These  
integrated monitoring and protection features provide a safe  
environment for microprocessors and other advanced low  
voltage circuits.  
Applications  
• Power Supply Control for Microprocessors  
• Low Output Voltage, High Current DC-DC Converters  
• Voltage Regulator Modules  
• Servers and Workstations  
• Memory and Accelerated Graphics Port Supplies  
• Communication Processor and Personal Computer
