HIP6521CB-T

Overview

The ISL6521CBZ-T is a PWM Buck DC/DC and Triple Linear Power Controller manufactured by Renesas (formerly Intersil). It utilizes a SOIC-16 package. The device operates with an input voltage range of 4.5 V to 5.5 V, featuring a nominal input of 5 V. It employs voltage-mode control and pulse width modulation techniques. The component is RoHS compliant and classified as a switching controller under EAR99 regulations.

Feature Summary

• Provides power control and protection for one PWM buck controller and three linear controllers.
• Regulates low voltage supplies requiring high current, typically core voltages for processors.
• Integrates monitoring capabilities for the primary PWM controller.

Applications

• Core voltage regulation for FPGAs
• Core voltage regulation for ASICs
• Core voltage regulation for processors

Procurement Notes

Verify the exact suffix against official documentation, as 'CBZ' indicates specific packaging and temperature ratings. Confirm lead times and stock availability directly with authorized distributors or the manufacturer. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a single-chip solution is required to manage both high-current core rails and multiple auxiliary I/O or memory voltages. It is suitable for designs prioritizing board space reduction over multi-phase interleaving architectures. Verify that the synchronous rectified buck topology meets the transient response requirements of the target processor.

Part Context

This controller belongs to the Intersil/Renesas family of microprocessor power management ICs. It serves as a specialized alternative to discrete regulator solutions, consolidating buck and linear regulation functions. Related components in this ecosystem often include companion gate drivers like the HIP6602 series for enhanced performance in higher current applications.
