ISL8033IRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8033IRZ-T7A is a dual-channel synchronous buck switching regulator manufactured by Renesas Electronics. It integrates two independent step-down converters within a compact 24-VFQFN exposed pad package. The device supports an input voltage range from 2.85V to 6V, delivering up to 3A per channel with adjustable output voltages between 0.8V and 6V. Operating at a fixed switching frequency of 1.1MHz, it ensures stable performance across industrial temperature ranges.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging configuration distinct from standard tube variants. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure compatibility with existing PCB footprint dimensions for the 24-QFN package type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated outputs are required from a single input source. The 1.1MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the total thermal dissipation remains within limits for the chosen enclosure environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL8033 family of dual synchronous buck regulators designed for space-constrained applications. It replaces older discrete solutions by integrating high-side and low-side drivers along with protection circuits into a single monolithic IC structure.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL8033IRZ serves as the non-reel variant of the same functional device. Cross-reference pinouts and electrical specifications carefully before substitution to ensure mechanical fit.
