Each phase delivers up to 25A of output current, based upon MOSFETselection. Each chip can be configured as two single-phase outputs or onedual-phase output. With the ability of each ISL8120 to deliver twosingle-phase 25A outputs or one dual-phase 50A output, designers determinethe number of ISL8120s required based on the number of voltage rails andoutput current levels that need to be generated. Up to six ISL8120s can beused in parallel to deliver a single 12-phase 300A output. The ISL8120'sintegrated current sharing control enables this unique scalability.

The ISL8120's versatility is further increased by its ability to handleindustry-standard input voltages of 3V, 9V, 12V and 24V. In addition, thedevice's gate drive voltage ranges from 2.7V to 5.5V, featuring a low-side2A/4A 5V drive and a 2A/2A 5V high-side drive. The controller can alsoperform overcurrent sensing by DC resistance (DCR), Rds(on) or externalsense resistance (ESR) so that it can function in a broad variety of systemarchitectures.

The ISL8120 also provides high accuracy by offering true differentialremote sensing. This is achieved by referencing from an individual nodepoint directly to ground and provides a higher degree of accuracy, allowingmore precise debugging of the layout.

Available now in a 32-lead QFN package, the ISL8120 is a perfect PWMcontroller solution for datacomm or telecomm systems, RAID systems, powermodules, power supplies or industrial applications.
