ISL8033AIRZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8033AIRZ is a dual-channel synchronous buck switching regulator IC manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.85V to 6V and provides two independent positive adjustable outputs, each capable of delivering up to 3A of current. The minimum output voltage is set at 0.8V, with a maximum adjustable limit of 6V. The device utilizes a fixed internal switching frequency of 1.1MHz. It is housed in a 24-VFQFN package with a bare thermal pad, measuring 4mm x 4mm, designed for surface-mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AIRZ' against the official datasheet to confirm temperature grade and packaging configuration. Ensure compatibility with RoHS3 standards if required by project specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated buck converters are needed within a single package footprint. The 1.1MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load requirements do not exceed the 3A per channel limit and that the input voltage remains within the specified 2.85V to 6V operational window for stable regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL8033 family of dual synchronous step-down regulators. It shares architectural similarities with other Renesas PMICs but is distinct due to its dual-output capability and specific 24-QFN packaging. The 'AIRZ' designation indicates automotive-grade reliability and tube packaging, differentiating it from standard commercial variants or tape-and-reel options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ISL8033IRZ for commercial grade applications. For tape-and-reel packaging needs, consider ISL8033AIRZ-T or ISL8033IRZ-T. Verify pinout compatibility and thermal characteristics when transitioning between these variants.
