      ISL6559CR-T
      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 rDS(ON) Current Sharing- Lossless- Low Cost• 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- 0.800V to 1.550V in 25mV Steps- Dynamic VID Technology• Programmable Droop Voltage• Fast Transient Recovery Time• Over Current Protection• 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• AMD Hammer Family Processor Voltage Regulator• Low Output Voltage, High Current DC-DC Converters• Voltage Regulator Modules
