Product Description

The ISL6247 provides microprocessor core-voltage

regulation by driving up to four interleaved synchronousrectified

buck-converter channels in parallel. Multi-phase

buck converter architecture uses interleaved timing to

multiply ripple frequency and reduce input and output ripple

currents. The reduction in ripple results in fewer

components, lower component cost, reduced power

dissipation, and smaller implementation area. The ISL6247

multi-phase controller together with ISL6207 gate drivers

forms the basis for a portable power supply solution to power

Intel’s next generation mobile microprocessors.

Intel Mobile Voltage Positioning (IMVP) is a smart voltage

regulation technology which effectively reduces power

dissipation in Intel® Pentium® Processors. The ISL6247

supports the IMVP-5 mobile processor voltage regulation

specifications. To boost battery life, the ISL6247 operates in

Active, Deep Sleep, or Deeper Sleep modes, depending

upon the logic levels at the DSEN# and DRSEN pins. A 6-bit

digital-to-analog converter (DAC) allows dynamic adjustment

of the core output voltage from 0.8375V to 1.6V. The

controller features a thermal monitor which sends a signal to

the microprocessor to reduce the load before power system

components exceed their maximum thermal limits, reducing

the thermal design complexity and overall core-voltage

regulation cost.

To improve efficiency, the ISL6247 allows users to select one

of two popular lossless current sense techniques. The

ISL6247 supports detection via inductor coil resistance

(DCR), or the rDS(ON) of the lower MOSFET. Either cost and

space-saving method provides feedback for precision droop,

channel current balancing, and individual channel

over-current protection. A unity gain, differential amplifier is

provided for remote voltage sensing. The differential

amplifier eliminates errors due to potential differences

between remote and local grounds. Eliminating ground

differences improves regulation and protection accuracy.

The channel switching frequency is adjustable in the range

of 200kHz to 1.0MHz, providing flexibility in managing the

balance between high-speed response, target efficiency, and

good thermal management.
