ISL6269BCRZ

DC DC Switching Controllers Overview

The ISL6269BCRZ is a synchronous buck DC-DC switching controller from Renesas Electronics, part of the Robust Ripple Regulator (R3) series. It operates with a supply voltage range of 7V to 25V and supports programmable switching frequencies between 200kHz and 600kHz. The device features a single positive output configuration housed in a 16-QFN (4x4 mm) package with an exposed pad. It includes integrated control characteristics such as enable, frequency control, phase control, and power good signaling. The component is rated for an operating temperature range of -10°C to 100°C.

DC DC Switching Controllers Feature Summary

• General-purpose high-current DC-DC step-down conversion

DC DC Switching Controllers Procurement Notes

Verify current availability status as the ISL6269BCRZ is officially listed as discontinued by the manufacturer. Confirm end-of-life notifications and product change notices prior to design finalization. Ensure compatibility with existing PCB footprints if transitioning from active inventory. Consult official distributor channels for last-time buy information or authorized replacement alternatives.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a single-phase synchronous buck solution with precise ripple regulation. The R3 technology offers advantages in dynamic load response compared to traditional PWM controllers. Consider the 16-QFN package constraints for thermal management and layout requirements. Evaluate the 200kHz to 600kHz frequency range against inductor size and efficiency targets.

DC DC Switching Controllers Part Context

This component belongs to the ISL6269 family of robust ripple regulator controllers designed for high-performance computing loads. It shares architectural similarities with other members like the ISL6269CRZ but may differ in specific electrical tolerances or testing criteria defined by the manufacturer. The series is characterized by its ability to maintain tight output voltage regulation under varying load conditions.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is discontinued, engineers must evaluate alternative synchronous buck controllers from the same or different manufacturers that match the pinout, electrical specifications, and thermal requirements.
