ISL6504ACRZ

Power Supply Controllers, Monitors Overview

The ISL6504ACRZ is a multiple linear power controller with an ACPI control interface, designed for microprocessor and computer applications. It integrates three linear controllers, switching, monitoring, and control functions within a 20-pin QFN 6x6 package. The device provides four ACPI-controlled voltage planes: 5VDUAL, 3.3VDUAL/3.3VSB, 1.2V VID, and 1.5VSB ICH4 Resume Well. It supports selectable operating modes via S3 and S5 digital pins to manage active or sleep states. Output voltage regulation is maintained at ±2.0% over temperature across all outputs.
