DATASHEET ISL9506 Multiphase PWM Controller with Programmable Output Voltage FN6722 Rev 0.00 August 13, 2008 The ISL9506 is a multiphase PWM buck controller for high performance digital processor core.

This multiphase buck controller uses interleaved channels to reduce the total output voltage ripple with each channel carrying a portion of total load current.

The multiple phase implementation results in better system performance, superior thermal management, lower component cost, reduced powe

ISL9506 Features

* ISL9506 reports output power through a power monitor pin (PMON). Current sense can be achieved by using either inductor DCR or discrete precision resistor. In the case of DCR current sensing, a single NTC thermistor is used to thermally compensate the inductor DCR variation with temperature. A unit
