HIP6521CBZA-T

Overview

The HIP6521CBZA-T is a PWM Buck DC/DC and Triple Linear Power Controller housed in a 16-pin SOIC package. It integrates one switching controller for synchronous rectified buck conversion and three linear regulators to manage core, I/O, and memory voltages. The device operates within an input voltage range of 4.5 V to 5.5 V, utilizing voltage-mode control with pulse width modulation technology.

Feature Summary

• Integrates a single PWM buck converter controller for high-current core voltage regulation
• Includes three dedicated linear power controllers for system auxiliary rails
• Provides comprehensive power management protection and monitoring capabilities

Applications

• FPGA core voltage regulation
• ASIC power supply control
• Processor voltage management

Procurement Notes

Verify the specific temperature range classification against the official Renesas datasheet prior to procurement, as standard specifications may vary by lot or revision. Confirm that the SOIC-16 package dimensions align with your PCB footprint requirements. Ensure compatibility with your system's 5V nominal input supply and validate thermal performance under maximum load conditions.

Selection Notes

Select this component when a combined solution for high-current digital core power and multiple lower-voltage analog or I/O rails is required. It is suitable for designs needing integrated protection features without external discrete controllers. Consider the SOIC-16 package size constraints and verify that the internal linear regulators meet the current demands of your peripheral circuits.

Part Context

This part belongs to the Intersil product line, now managed by Renesas Electronics Corporation. It is designed for applications requiring precise power sequencing and regulation for complex digital logic devices. The integration of buck and linear controls simplifies the bill of materials for multi-rail power systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas portfolio that offer updated process technologies or extended temperature ranges if available.
