ISL6549CAZA-T

Overview

The ISL6549CAZA-T is a dual regulator power controller featuring a synchronous rectified buck PWM controller and a linear LDO, designed for single 12V input supply applications. It operates within a switching frequency range of 150 kHz to 1 MHz and supports an output voltage range of 800 mV to 13.2 V. The device provides up to 20 A of output current and functions at temperatures from 0°C to +70°C. Packaged in a 14-SOIC (Narrow) format, it integrates two outputs with 100% maximum duty cycle capability.

Feature Summary

Integrates a synchronous rectified buck PWM controller and a linear LDO regulator into a single component.
Operates on a single 12V input supply, simplifying system power architecture requirements.
Supports wide switching frequency adjustment from 150 kHz to 1 MHz for optimized design flexibility.

Applications

Desktop PC motherboard power distribution
Server and workstation voltage regulation modules
Industrial equipment requiring dual voltage rails

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging versus tube variants when sourcing. Confirm RoHS compliance status through official Renesas documentation as specifications may vary by production lot. Ensure the 14-SOIC narrow package dimensions align with PCB footprint constraints prior to final procurement decisions.

Selection Notes

Select this component for designs requiring simultaneous high-current buck conversion and precise low-voltage LDO regulation from a single 12V source. Evaluate thermal management needs given the 20A output capacity and SOIC package limitations. Consider the 150kHz-1MHz frequency range against EMI requirements and external inductor selection criteria.

Part Context

Part of the ISL6549 series, which combines synchronous buck and linear technologies for comprehensive power management. This family targets multi-rail systems needing efficient voltage translation. The CAZA variant specifies specific package and environmental ratings within the broader controller lineup.
