Overview
The AOZ2150EQI-30 is a high-efficiency synchronous buck regulator from the EZBuck series by Alpha & Omega Semiconductor. It operates with an input voltage range of 6.5V to 28V and provides a single adjustable output from 0.8V to 7.5V at up to 3A. The device integrates a 1MHz switching frequency and employs constant on-time control for fast transient response. Packaged in a compact 18-QFN (3x3) surface-mount footprint, it supports operation across a -40°C to 85°C ambient temperature range.
Feature Summary
- Integrates synchronous rectification for improved power conversion efficiency
- Utilizes Constant On-Time (COT) architecture for rapid load transient response
- Features light load mode operation to enhance efficiency under low current conditions
- Includes internal compensation and protection mechanisms for simplified design
Applications
- Point-of-load regulation for embedded systems
- Voltage translation in industrial equipment
- Power supplies for consumer electronics
- Battery-powered devices requiring efficient step-down conversion
Procurement Notes
Verify the specific suffix EQI-30 against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure that the selected supplier sources genuine components directly from Alpha & Omega Semiconductor or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance status if required for your manufacturing process.
Selection Notes
Select this component when a compact solution is needed for converting higher bus voltages down to lower logic levels. The 18-QFN package suits space-constrained designs. Consider the 3A output capability and 28V maximum input rating to ensure adequate headroom for your specific application requirements and thermal management capabilities.
Part Context
This part belongs to the EZBuck family of synchronous regulators designed for ease of use and high performance. It complements other variants like the AOZ2151EQI-30, which offers similar topology but different current ratings. The series targets applications demanding small footprints without sacrificing efficiency or transient performance.
Replacement Considerations
Direct substitutes include the AOZ2151EQI-30 for higher current needs. Verify pin-to-pin compatibility before replacing. Other compatible options may exist within the same manufacturer's portfolio; consult official cross-reference guides for validated alternatives.
