ISL8118CRZ-T

DC DC Switching Controllers Overview

The ISL8118CRZ-T is a synchronous buck switching controller manufactured by Renesas Electronics Corporation, formerly Intersil. It operates within a switch frequency range of 250 kHz to 2 MHz and supports an output current of 30 A. The device regulates output voltages between 600 mV and 20 V with a maximum duty cycle of 100%. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a QFN-EP-28 package and is classified as a single-output switching controller.

DC DC Switching Controllers Feature Summary

• Supports high-frequency operation up to 2 MHz for compact passive design
• Capable of delivering up to 30 A output current for high-power applications
• Enables full load transient response with 100% maximum duty cycle capability

DC DC Switching Controllers Applications

• Industrial point-of-load (POL) power supplies
• General purpose voltage regulation systems
• High-density computing power architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'CRZ' against official datasheets to confirm temperature grade and packaging details. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may apply. Ensure compatibility with existing PCB footprints for the QFN-EP-28 package before procurement.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high current delivery and wide input voltage flexibility. Consider the thermal performance of the QFN-EP-28 package for heat dissipation requirements. Evaluate the need for external components versus integrated solutions based on system complexity and cost targets.

DC DC Switching Controllers Part Context

This component belongs to the ISL8118 series of synchronous buck controllers. It is part of Renesas's portfolio of power management integrated circuits designed for industrial and general-purpose markets. The series emphasizes efficiency and dynamic response for modern power distribution networks.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the ISL8117 or ISL8119 families if available. Verify that substitute parts meet the same 30 A current rating and 2 MHz frequency specifications.
