Digital Multiphase Controller
The ISL6595 digital multiphase controller provides core
power for today’s high current microprocessors by driving up
to six synchronous-rectified buck-converter channels in
parallel. Interleaved timing of the channels results in a higher
ripple frequency, reducing input and output ripple. With up to
six phases, each capable of up to 2MHz operation, the
ISL6595 can be used to build DC/DC converters that provide
up to 200A with excellent efficiency, low ripple, and the
lowest component count.
The ISL6595 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
stability. The ISL6595 incorporates an industry standard I
serial interface for control and monitoring. Through the serial
interface, the power supply designer can quickly optimize
designs and monitor parameters. The interface allows the
ISL6595 to provide digitized information for real time system
monitoring and control.
The ISL6595 provides superior loadline accuracy through
internal calibration that measures and corrects current sense
error sources upon start-up. The ISL6595 has
programmable current sense temperature compensation
that allows the designer to tailor the response for best
loadline accuracy over-temperature. Superior loadline
accuracy reduces component count and solution cost.
To further reduce component count the ISL6595
incorporates patented Active Transient Response (ATR)
technology, allowing the fastest response to transient events
for reduced output capacitance.
The flexibility of the ISL6595 allows the power supply
designer to implement a wide range of solutions. When used
with industry standard power train components, the ISL6595
provides the highest performance with lowest component
count and cost.
