AOZ5273QI-01

Overview

The AOZ5273QI-01 is a high-performance Smart Power Stage (SPS) manufactured by Alpha & Omega Semiconductor Inc. It integrates two asymmetrical MOSFETs and an integrated driver designed for high-current, high-frequency DC-DC converters. The device operates within a voltage input range of 3V to 20V. Key electrical specifications include a current monitor with ±5% accuracy and high/low-side sensing methods. The component is housed in a compact package suitable for surface mount applications.

Feature Summary

Integrates two asymmetrical MOSFETs with an embedded driver for simplified design
Provides current monitoring capability with specified accuracy
Supports high-current and high-frequency DC-DC conversion applications

Applications

High-current DC-DC converters
High-frequency power supply stages
General-purpose smart power stage implementations

Procurement Notes

Verify the specific -01 suffix against official Alpha & Omega documentation to confirm pinout and functional equivalence with standard variants. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the selected packaging matches production requirements. Check for obsolescence notices as this series may have limited availability for new designs.

Selection Notes

Select this component when a compact solution combining gate drive and power switching is required. The asymmetrical MOSFET configuration optimizes performance for specific duty cycles. Verify that the 3V to 20V input range aligns with the system logic levels. Consider the thermal characteristics of the package for the intended current load.
