AOZ5507QI

Overview

The AOZ5507QI is a high-efficiency synchronous buck power stage module manufactured by Alpha & Omega Semiconductor Inc. It integrates two asymmetrical MOSFETs and an integrated driver within a compact 22-QFN (4.5x3.5 mm) package. The device supports a load voltage range of up to 25V and delivers an output current of 30A per channel, with a peak output capability of 60A. Designed for DrMOS applications, it features FCCM control and operates across a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates asymmetrical MOSFETs and driver in a single module
• Supports Fast Cross-Conduction Control (FCCM)
• Includes bootstrap circuit and diode emulation

Applications

• Synchronous buck converters
• Point-of-load (POL) regulation
• Server and storage systems

Procurement Notes

Verify the specific suffix and package dimensions against the official datasheet to ensure compatibility with your PCB footprint. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to integration. Check for obsolescence notices as this component may be subject to design-in restrictions or end-of-life transitions.

Selection Notes

Select this component for designs requiring a compact solution with integrated gate drive and power stages. Ensure the input voltage and load current requirements fall within the 25V and 30A limits respectively. Verify thermal management capabilities given the small QFN package size and high current density.

Part Context

This part belongs to the AOZ55xx series of DrMOS modules from Alpha & Omega Semiconductor. These modules are designed to simplify power supply design by combining power switches and drivers. The AOZ5507QI specifically targets applications needing moderate current levels in a small form factor.

Replacement Considerations

Potential substitutes include AOZ5007AQI or AOZ5317NQI, though pinouts and electrical characteristics must be verified against the original design requirements.
