Overview
The AOZ1021HAIL_2 is a positive adjustable buck switching regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It delivers up to 3A output current with an input voltage range of 4.5V to 16V and an adjustable output starting at 0.8V. Operating at a fixed 500kHz switching frequency, it features synchronous rectification for improved efficiency. The device is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm) and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrated synchronous rectification for enhanced power conversion efficiency
- Fixed 500kHz switching frequency enables compact external component sizing
- Adjustable output voltage starting from 0.8V for flexible system design
Applications
- Point-of-load regulation for embedded systems
- Battery-powered portable devices requiring efficient step-down conversion
- Industrial control modules needing stable 3A supply rails
Procurement Notes
Verify the exact suffix HAIL_2 against manufacturer documentation, as suffixes often denote specific tape-and-reel packaging or environmental compliance variations. Confirm RoHS status and moisture sensitivity level requirements for your assembly process. Cross-reference the DigiKey part number 785-1155-2-ND for accurate ordering details and availability status.
Selection Notes
Select this component when a 3A synchronous buck solution is required within a 16V input limit. The 8-SOIC package offers a larger footprint than DFN options, potentially easing manual assembly or rework. Ensure the application benefits from the 500kHz frequency trade-off between size and EMI compared to lower-frequency alternatives.
Part Context
This part belongs to the EZBuck family of non-synchronous and synchronous buck regulators. While similar to the AOZ1014DI which offers 5A current in a smaller DFN package, the AOZ1021HAIL_2 provides 3A in an SOIC package with integrated synchronous rectification, distinguishing it from non-synchronous variants in the same series.
Replacement Considerations
Publicly confirmed substitutes include the AOZ6689CI. Verify pinout compatibility and thermal performance before substitution, as package differences may impact PCB layout and heat dissipation requirements.
