Overview
The AOZ1282CI is a synchronous step-down switching regulator IC from Alpha & Omega Semiconductor Inc., part of the EZBuck series. It delivers an adjustable output voltage ranging from 0.8V to 36V with a maximum continuous output current of 1.2A. The device operates within an input voltage range of 4.5V to 36V and features a fixed switching frequency of 450kHz. Designed for surface-mount applications, it utilizes an SOT-23-6 package and supports an operating ambient temperature range of -40°C to 85°C.
Feature Summary
- Integrated simple buck topology requiring minimal external components
- Adjustable output voltage capability across a wide range
- Fixed high-frequency switching operation for compact design
Applications
- Portable consumer electronics power supplies
- Battery-powered devices requiring efficient voltage regulation
- General-purpose DC-DC conversion in industrial systems
Procurement Notes
Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm package integrity and marking consistency against official datasheet specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Validate lot traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a compact, low-current buck solution is required for inputs up to 36V. The fixed 450kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal performance constraints given the small SOT-23-6 package size under load conditions.
Part Context
This regulator belongs to the EZBuck family, designed for simplicity and ease of implementation. It targets applications needing reliable power management without complex control loops. The manufacturer specializes in power management integrated circuits for various electronic sectors.
Replacement Considerations
Check for direct pin-compatible substitutes within the same EZBuck series, such as the AOZ1282DI or AOZ1282PI, which offer identical electrical characteristics but different packaging options suitable for alternative board layouts.
