ISL6592 6-Phase Digital Multiphase Controller

® ISL6592 Data Sheet August 5, 2005 FN9163.1 6-Phase Digital Multiphase Controller The ISL6592 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 1.5MHz operation, the ISL6592 can be used to build DC/DC converters that provide.

ISL6592 Features

* Multiphase power conversion - 2- to 6-phase operation

* 300kHz to 1.5MHz switching frequency

* Supports Intel® VR 10.x, AMD®, and custom VID codes

* Internal high precision voltage reference - ±5mV voltage setpoint accuracy

* Precision digital current sense
