FN9227 Rev 1.00 Dec 12, 2006 ISL6316 Enhanced 4-Phase PWM Controller with 6-Bit VID Code Capable of Precision rDS(ON) or DCR Differential Current Sensing for VR10 Application DATASHEETThe ISL6316 controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates. The ISL6316 features a high bandwidth control loop and ripple frequencies up to >4MHz to provide optimal response to the transients. Today’s microprocessors require a tightly regulated output voltage position versus load current (droop). The ISL6316 senses current by utilizing patented techniques to measure the voltage across the on resistance, rDS(ON), of the lower MOSFETs or DCR of the output inductor during the lower MOSFET conduction intervals. Current sensing provides the needed signals for precision droop, channel-current balancing, and overcurrent protection. A programmable internal temperature compensation function is implemented to effectively compensate for the temperature coefficient of the current sense element. A unity gain, differential amplifier is provided for remote voltage sensing. Any potential difference between remote and local grounds can be completely eliminated using the remote- sense amplifier. Eliminating ground differences improves regulation and protection accuracy. The threshold-sensitive enable input is available to accurately coordinate the start up of the ISL6316 with any other voltage rail. Dynamic-VID™ technology allows seamless on-the-fly VID changes. The offset pin allows accurate voltage offset settings that are independent of VID setting. Features • Precision Multiphase Core Voltage Regulation - Differential Remote Voltage Sensing - 0.5% System Accuracy Over Life, Load, Line and Temperature - Adjustable Precision Reference-Voltage Offset • Precision rDS(on) or DCR Current Sensing - Accurate Load-Line Programming - Accurate Channel-Current Balancing - Differential Current Sense • Microprocessor Voltage Identification Input - Dynamic VID™ Technology - 6-Bit VID Code at 12.5mV per Bit - 0.8375V to 1.600V Operation Range • Thermal Monitoring • Programmable Temperature Compensation • Threshold-Sensitive Enable Pins to Enable VR and Ensure Power Sequencing Control • Overcurrent Protection • Overvoltage Protection • 2, 3 or 4 Phase Operation • Adjustable Switching Frequency up to 1MHz per Phase • Package Option - QFN Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat No Leads - Product Outline - QFN Near Chip Scale Package Footprint; Improves PCB Efficiency, Thinner in Profile • Pb-Free Plus Anneal Available (RoHS Compliant) Ordering Information PART NUMBER/ PART MARKING TEMP.
