Overview
The AOZ1268QI-01 is a synchronous step-down DC/DC converter from Alpha & Omega Semiconductor. It operates with an input voltage range of 6.5V to 28V and delivers a continuous output current of 10A. The device provides an adjustable output voltage ranging from 0.8V to 23.8V in a single-output configuration. It utilizes the EZBuck technology for high efficiency and ease of use. The component is housed in a 23-pin PowerTFQFN package, designed for compact power management applications requiring reliable voltage regulation.
Feature Summary
- Synchronous buck regulator architecture for high efficiency
- EZBuck technology simplifies design implementation
- Wide input voltage capability up to 28V
- Adjustable output voltage control
Applications
- Industrial equipment power distribution
- Telecommunications infrastructure systems
- Consumer electronics power supplies
- Embedded computing modules
Procurement Notes
Verify the exact part marking and datasheet revision against official Alpha & Omega Semiconductor documentation. Confirm the suffix -01 corresponds to the specific package and temperature grade required. Ensure compatibility with existing PCB footprints for the 23-PowerTFQFN package. Cross-reference ordering information directly with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a 10A synchronous buck solution is needed within a 28V input limit. The adjustable output allows flexibility for various load requirements between 0.8V and 23.8V. Consider the thermal performance of the PowerTFQFN package for the intended enclosure environment. Evaluate system efficiency needs against the EZBuck topology benefits.
Part Context
This device belongs to the AOZ1268 series of synchronous buck regulators. The series focuses on high-efficiency power conversion for space-constrained designs. The -01 suffix typically denotes specific packaging or testing variations within the product line. It serves as a core power management integrated circuit for converting higher bus voltages to lower logic or peripheral supply levels.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that substitute parts maintain the 10A current rating and 28V maximum input specification. Ensure the replacement supports the required output voltage range and package dimensions.
