AOZ6663DI

Product Overview

The AOZ6663DI from Alpha & Omega Semiconductor Inc. is an Active EZBuck™ step-down switching regulator IC for positive adjustable output. It accepts 4.5V to 18V input and provides a single output adjustable from 0.6V to 6V at up to 3A. It uses 750kHz switching with synchronous rectification and is supplied in an 8-SMD, Flat Leads Exposed Pad package, supplier device package 8-DFN-EP (3x3), for surface mount assembly.

Key Features

• Buck topology with synchronous rectification for step-down conversion from a 4.5V to 18V input.
• Single positive adjustable output: 0.6V minimum to 6V maximum, rated for 3A output current.
• Switching frequency of 750kHz and operating temperature range of -40°C to 85°C (TA).
• 8-SMD, Flat Leads Exposed Pad package, supplier device package 8-DFN-EP (3x3), surface mount.

Applications

• Board-level power conversion from a higher intermediate rail to a lower regulated rail in general electronic equipment.
• Adjustable 0.6V to 6V output for powering logic, I/O, or memory subsystems within a 3A budget.
• Compact surface-mount DC-DC conversion where a single-output buck regulator with exposed pad is suitable.

Design & Procurement Notes

Designers selecting the AOZ6663DI should verify that the system input remains within 4.5V to 18V and that the required output stays within 0.6V to 6V at no more than 3A. The 750kHz switching frequency and 8-DFN-EP (3x3) exposed-pad package support compact surface-mount layouts, while the -40°C to 85°C (TA) range defines the supplied ambient operating limit. The listed lifecycle status is Active.
