AOZ1236QI-01

Overview

The AOZ1236QI-01 is a synchronous step-down DC-DC converter from Alpha & Omega Semiconductor, part of the EZBuck family. It integrates high-side and low-side N-channel power MOSFETs with a fixed-frequency current-mode controller. The device supports an input voltage range up to 28V and delivers a continuous output current of 6A. It features adjustable output voltage via external resistors and includes comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown.

Feature Summary

• Integrated synchronous rectification with internal high and low-side MOSFETs for high efficiency
• Fixed-frequency current-mode control architecture for stable operation
• Built-in protection against over-current, over-voltage, and thermal events

Applications

• Point-of-load regulation in computing systems
• Power supply stages for graphics cards
• Voltage conversion for data center equipment
• General-purpose DC-DC conversion in industrial electronics

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and temperature grade.
