AOZ1269QI-2

Overview

The AOZ1269QI-2 is a synchronous step-down DC/DC converter from Alpha & Omega Semiconductor. It delivers up to 12A output current with a maximum output voltage of 23.8V. The device operates within an input voltage range of 2.7V to 28V and supports switching frequencies between 200kHz and 1MHz. Designed for reliability, it functions across an operating temperature range of -40°C to 85°C (TA). This integrated solution combines high efficiency with compact packaging suitable for space-constrained applications.

Feature Summary

Integrated synchronous rectification for enhanced power conversion efficiency
Wide input voltage capability supporting diverse power supply architectures
Adjustable switching frequency allowing optimization for size or performance

Applications

Point-of-load regulation in industrial equipment
Power distribution units for computing infrastructure
Battery-powered portable devices requiring stable voltage rails

Procurement Notes

Verify the specific suffix 'QI-2' against official Alpha & Omega Semiconductor documentation to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference ordering information directly with authorized distributors to avoid counterfeit components and ensure traceability throughout the supply chain.

Selection Notes

Select this component when a 12A synchronous buck regulator is required within a 28V input limit. Consider the QFN package for thermal management needs and board space constraints. Evaluate the 200kHz to 1MHz frequency range against EMI requirements and external inductor sizing limitations for the specific application environment.

Part Context

This part belongs to the EZBuck family of regulators, designed for high-current applications. It integrates power switches and control logic into a single compact module. The series targets modern electronics needing efficient voltage translation from higher bus voltages to lower digital core levels.
