HIP6521CB

Overview

The HIP6521CB is a PWM Buck DC/DC and Triple Linear Power Controller manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 4.5 V to 5.5 V, with a nominal input of 5 V. The device utilizes voltage-mode control and pulse width modulation techniques. It is housed in a 16-pin SOIC package (SOP, SOP16,.25) with a length of 9.9 mm. The component is RoHS compliant and classified as a switching controller under ECCN code EAR99.

Feature Summary

• Provides power control and protection for one synchronous rectified buck converter and three linear controllers.
• Regulates low voltage supplies requiring high current, typically for FPGA, ASIC, or processor core voltages.
• Manages system voltages such as I/O and memory circuits through integrated linear regulators.

Applications

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

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm temperature range and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 16-pin SOIC package. Cross-reference datasheet revisions to validate pinout consistency before integration into new designs.

Selection Notes

Select this controller for applications requiring a single high-current buck regulator alongside multiple lower-power linear outputs. It is suitable for systems needing integrated protection features for core and peripheral voltages. Evaluate thermal performance requirements based on the SOIC package constraints.

Part Context

This component belongs to the family of power management ICs designed for complex digital systems. It integrates both switching and linear regulation capabilities to simplify power distribution networks. The device addresses the need for precise voltage regulation in multi-rail systems common in computing and communication hardware.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic equivalents may not match the specific control loop characteristics or protection thresholds required for sensitive FPGA or ASIC cores.
