ISL78264ARZ-T7A

DC DC Switching Controllers Overview

The ISL78264ARZ-T7A is an automotive-grade dual synchronous buck controller IC from Renesas Electronics designed for step-down DC-DC power conversion. It operates within a VIN range of 2.1 to 42V and features a switching frequency adjustable between 200kHz and 2.2MHz. The device typically draws 6μA quiescent current in the buck channel. It is housed in a 32-QFN (5x5) package.

DC DC Switching Controllers Feature Summary

• Automotive-grade reliability for vehicle applications
• Dual synchronous buck control topology
• Adjustable switching frequency up to 2.2MHz

DC DC Switching Controllers Applications

• Automotive power management systems
• High-performance industrial power solutions

DC DC Switching Controllers Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when ordering. Confirm the automotive grade designation aligns with target application requirements. Ensure compatibility with existing PCB footprints for the 32-QFN package. Check for updated datasheets regarding any recent manufacturing changes.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual independent buck outputs in an automotive environment. Consider the 2.1V to 42V input range for varying supply conditions. Evaluate thermal performance given the 5x5mm package size. Compare against single-channel alternatives if only one output is needed.

DC DC Switching Controllers Part Context

This part belongs to the ISL7826x series of automotive power controllers. It complements other variants like the ISL78263 and ISL78264 by offering dual buck capabilities. The series targets high-efficiency power distribution in modern electronic architectures.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other automotive-grade dual buck controllers from Renesas or compatible vendors. Verify pin-to-pin compatibility before substitution. Ensure equivalent electrical specifications are met.
