HIP6521CBZA

Overview

The Intersil HIP6521CBZA is a PWM Buck DC/DC and Triple Linear Power Controller housed in a 16-pin SOIC package. It integrates a synchronous rectified buck converter for regulating high-current core voltages, such as those for FPGAs, ASICs, or processors. The device also includes three linear controllers to manage system I/O and memory circuits. It operates within an input voltage range of 4.5 V to 5.5 V and utilizes voltage-mode control with pulse width modulation technology.

Feature Summary

• Integrates a synchronous rectified buck converter for primary core voltage regulation
• Includes three dedicated linear power controllers for auxiliary system rails
• Provides comprehensive power control and protection monitoring functions

Applications

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

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance and RoHS status according to the official datasheet. Confirm the operating temperature range details directly from the manufacturer's documentation, as general specifications may vary by revision. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring integrated control for both high-current digital cores and multiple lower-voltage analog or I/O rails. It is suitable for applications needing a single controller solution to simplify board space and reduce component count compared to discrete regulator designs.

Part Context

Originally developed by Intersil, this part is now managed under Renesas Electronics following the corporate acquisition. The HIP6521 series belongs to the family of power distribution controllers designed for complex digital logic devices. It represents the transition period where Intersil branding was retained on specific product lines before full integration into the Renesas portfolio.

Replacement Considerations

Consult Renesas Product Legacy Documents for confirmed substitute part numbers. Verify pin compatibility and electrical specifications against current Renesas offerings.
