AOZ5007QI

Overview

The AOZ5007QI is a high-current, high-performance DrMOS power module manufactured by Alpha & Omega Semiconductor Inc. It integrates a single-phase synchronous buck converter with an N-channel MOSFET output stage. The device supports input voltages from 4.5V to 27V and delivers up to 35A of continuous output current. It features a 31-PowerVFQFN package for surface mount installation. The module includes integrated bootstrap circuitry, diode emulation mode, and status flags for system monitoring.

Feature Summary

• Integrates a high-performance N-channel MOSFET half-bridge with gate driver in a compact PowerVFQFN module.
• Supports diode emulation mode to enhance light-load efficiency during discontinuous conduction.
• Includes built-in bootstrap circuitry to simplify external component requirements.
• Provides status flag outputs for real-time operational monitoring and fault detection.

Applications

• High-density server and workstation voltage regulation modules
• Graphics processing unit (GPU) core power delivery
• Central processing unit (CPU) point-of-load conversion
• Telecommunications base station power systems

Procurement Notes

Verify the specific suffix 'QI' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS compliance status. Confirm that the 31-PowerVFQFN footprint matches the target PCB design. Check for any recent obsolescence notices or recommended new designations from Alpha & Omega Semiconductor before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high current density in a small form factor. Ensure the thermal management solution can handle the power dissipation associated with 35A loads. Verify that the control loop stability is maintained when using the integrated driver characteristics. Compare performance metrics against alternative DrMOS solutions if lower current ratings are sufficient for the design.
