ISL68301IRAZ-T

DC DC Switching Controllers Overview

The ISL68301IRAZ-T is a single-phase full digital DC-DC buck controller IC from Renesas Electronics. It operates with an input voltage range of 4.75V to 16V and features a 24-pin QFN (4x4) package. The device provides PWM outputs for external MOSFET driving, eliminating integrated drivers found in similar models. It supports PMBus communication for configuration and monitoring. The controller utilizes a high-speed current share bus to parallel up to eight units for multi-phase applications exceeding 240A.

DC DC Switching Controllers Feature Summary

• Full digital control architecture enabling precise regulation and flexible configuration via software.
• PMBus interface support for comprehensive system monitoring, fault logging, and dynamic adjustment.
• High-speed current share bus capability allowing parallel operation of multiple controllers for high-current scalability.

DC DC Switching Controllers Applications

• Data center power supply designs
• Wired communications infrastructure equipment
• Wireless communications base stations

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 24-QFN package dimensions match your PCB footprint requirements. Ensure compatibility with your target input voltage range of 4.75V to 16V. Check for updated datasheet revisions to confirm pinout consistency with existing designs.

DC DC Switching Controllers Selection Notes

Select this component when a single-phase digital solution with PMBus is required. Choose over integrated driver versions if external MOSFETs are preferred for thermal management or cost optimization. Consider parallel configurations using the current share bus for higher current demands beyond single-phase capabilities.

DC DC Switching Controllers Part Context

This part belongs to the ISL6830x family of scalable digital PWM controllers. It complements the ISL68300, which integrates MOSFET drivers, by offering discrete PWM outputs. The family targets high-efficiency, digitally controlled power conversion systems requiring advanced monitoring and scalability through phase paralleling.

DC DC Switching Controllers Replacement Considerations

The ISL68300IRAZ serves as a functional alternative if integrated MOSFET drivers are acceptable. Verify pin-to-pin compatibility and software register mapping differences between the PWM output model and the integrated driver variant before substitution.
