ISL6521CBZS2698

Overview

The ISL6521CBZS2698 is a PWM Buck DC/DC and Triple Linear Power Controller manufactured by Intersil, now part of Renesas Electronics. It operates within a supply voltage range of 4.5V to 5.5V and utilizes a 16-lead SOIC package. The device integrates one synchronous buck controller for high-current loads and three linear regulators for auxiliary system voltages.

Feature Summary

• Integrates a synchronous rectified buck converter controller for primary core voltage regulation
• Includes three dedicated linear controllers for I/O and memory circuit power supplies
• Provides comprehensive power control and protection mechanisms for the system

Applications

• FPGA core voltage regulation
• ASIC processor power management
• System I/O voltage distribution
• Memory circuit power supply control

Procurement Notes

Verify the specific suffix 'S2698' against official Renesas documentation to confirm exact marking or tape-and-reel specifications. Ensure compatibility with the standard ISL6521CBZ electrical parameters. Confirm RoHS compliance status and moisture sensitivity level prior to procurement.

Selection Notes

Select this component when a single IC solution is required to manage both high-current digital cores and multiple lower-current analog peripherals. It simplifies board design by consolidating buck and linear regulation functions into one package, reducing external component count compared to discrete solutions.

Part Context

This part belongs to the ISL6521 family of power controllers designed for low-voltage applications. It serves as a central power management unit in systems requiring precise voltage regulation for complex digital logic and peripheral interfaces, typically found in computing and communication equipment.

Replacement Considerations

Check for direct replacements such as ISL6521IBZ or ISL6521CBZ. Verify pinout compatibility and thermal performance requirements before substituting.
