ISL6563CRZ-T

Special Purpose Regulators Overview

The ISL6563CRZ-T is a two-phase multiphase buck PWM controller with integrated MOSFET drivers, designed for advanced microprocessor voltage regulation. It operates within an input voltage range of 4.75V to 12V and supports output voltages from 0.8V to 1.85V. The device delivers up to 60A of output current per rail with a switching frequency of 255 kHz and a maximum duty cycle of 66%. Packaged in a 24-lead QFN EP (4x4 mm) surface-mount format, it functions at operating temperatures between 0°C and +70°C.

Special Purpose Regulators Feature Summary

• Integrates dual high-side and low-side MOSFET drivers to reduce external component count
• Provides precision voltage regulation through multiphase power conversion architecture
• Supports current mode PWM control for stable operation under dynamic loads

Special Purpose Regulators Applications

• Intel VRM9 and VRM10 processor power systems
• AMD Hammer application voltage regulation
• Advanced microprocessor core voltage regulation

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the tube-packaged 'ISL6563CRZ'. Confirm RoHS compliance status as documentation varies by source. Check lifecycle status as some listings indicate obsolete or end-of-life conditions. Ensure moisture sensitivity level (MSL) handling requirements are met during storage and assembly processes.

Special Purpose Regulators Selection Notes

Select this component when designing two-phase buck converters for Intel or AMD processors requiring integrated gate drive capabilities. Compare against single-phase alternatives if higher current density is needed. Consider thermal performance within the QFN package for PCB layout optimization. Verify compatibility with target microprocessor VID signals for proper voltage tracking.
