ISL8033AIRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8033AIRZ-T is a dual-output synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.85V to 6V and provides two adjustable output channels, each capable of delivering up to 3A of current. The device utilizes a fixed internal switching frequency of 1.1MHz and supports an output voltage range starting from 0.8V up to 6V. Packaged in a compact 24-VFQFN exposed pad form factor, it is designed for high-efficiency power conversion in space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the 'AIRZ' designation aligns with required temperature ratings and RoHS compliance standards for your manufacturing process. Cross-reference the datasheet revision history to ensure compatibility with existing design specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a dual-channel solution is required to save board space compared to using two separate single-output regulators. Ensure the input voltage remains within the 2.85V to 6V window and that the total thermal dissipation from two 3A outputs can be managed via the exposed pad. Verify that the 1.1MHz frequency does not interfere with sensitive RF circuits in the design.
