Overview
The AOZ1212AI is a 3A simple buck regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It operates with an input voltage range of 4.5V to 27V and provides an adjustable output voltage from 0.8V to 22.95V. The device features a fixed switching frequency of 370kHz and delivers up to 3A of continuous output current. It is housed in an 8-SOIC package (0.154" width) and supports surface mount installation. The component functions as a positive, non-synchronous DC-DC converter suitable for various power management applications.
Feature Summary
- Integrated 3A buck regulator topology
- Adjustable output voltage capability
- Fixed 370kHz switching frequency operation
Applications
- General purpose DC-DC conversion
- Point-of-load regulation
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'AI' corresponds to the 8-SOIC package variant. Confirm current availability status as the product may be marked as not recommended for new designs. Check for any recent Product Change Notifications regarding assembly or material updates before finalizing procurement plans.
Selection Notes
Select this component when a fixed-frequency, non-synchronous buck solution is required for inputs up to 27V. Ensure the thermal requirements of the 8-SOIC package are met for the expected load current. Compare against synchronous alternatives if higher efficiency at light loads is critical for the specific application design.
Part Context
This part belongs to the EZBuck family of simple buck regulators designed for ease of implementation. It shares functional similarities with other members like the AOZ1212DI but differs in packaging. The series targets cost-sensitive applications requiring reliable step-down conversion without complex external compensation networks.
Replacement Considerations
Direct pin-compatible replacements within the same package include the AOZ1212DI variant. Other compatible options from the EZBuck family such as the AOZ1012D or AOZ1013 may serve as functional substitutes depending on specific pinout and thermal constraints.
