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 I2C 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 startup. 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.
