AOZ2152EQI-29

Overview

The AOZ2152EQI-29 is a synchronous buck switching regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It features a wide input voltage range of 6.5V to 28V and delivers a maximum continuous output current of 5A. The device provides a positive, adjustable output voltage starting from a minimum of 0.8V up to 23.8V. Operating with a fixed switching frequency of 1MHz, it utilizes an 18-PowerWFQFN (3x3mm) surface-mount package. The component supports operation across a temperature range of -40°C to 85°C ambient.

Feature Summary

• Integrated high-efficiency synchronous rectification for improved power conversion performance
• Fixed 1MHz switching frequency enables the use of compact external components
• Wide input voltage tolerance accommodates various supply rail variations
• Compact 3x3mm QFN footprint optimizes board space utilization

Applications

• Point-of-load regulation for embedded systems
• Industrial control equipment power distribution
• Consumer electronics DC-DC conversion stages
• Communication infrastructure power supplies

Procurement Notes

Verify the specific suffix EQI-29 against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the selected packaging format matches production line capabilities. Cross-reference datasheet revisions to validate parameter consistency.

Selection Notes

Select this component when a 5A output capability within a 6.5V to 28V input range is required. The 1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Evaluate thermal performance requirements given the 3x3mm package size under full load conditions. Ensure the target application operates within the specified -40°C to 85°C ambient temperature limits.

Part Context

This part belongs to the EZBuck family of synchronous regulators designed for high-density applications. The series emphasizes efficiency and small solution size through integrated power switches and optimized control loops. The AOZ2152 variant specifically targets 5A loads, distinguishing it from lower-current counterparts in the same product line.

Replacement Considerations

Check for direct substitutes within the same EZBuck family or comparable 5A synchronous buck regulators from other manufacturers. Verify pin compatibility and thermal pad configurations if replacing on existing PCBs. Ensure equivalent input/output voltage ranges and switching frequencies are maintained.
