AOZ1212DI

Overview

The AOZ1212DI is a DC-DC buck switching regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It features an adjustable output voltage range from 0.8V to 22.95V with a maximum continuous output current of 3A. The device operates with an input supply voltage between 4.5V and 27V. It utilizes a fixed switching frequency of 370kHz and does not include synchronous rectification. The component is housed in an 8-VDFN package with an exposed pad, measuring 4x5mm, and supports surface-mount installation.

Feature Summary

Integrates a non-synchronous buck converter topology for efficient step-down voltage regulation
Provides adjustable output voltage control within a wide operational range
Supports analog dimming and PWM dimming capabilities for precise load management

Applications

Portable consumer electronics requiring compact power solutions
Battery-powered devices needing efficient voltage regulation
General-purpose embedded systems utilizing standard logic levels

Procurement Notes

Verify the specific suffix 'DI' to confirm the 8-DFN package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for End-of-Life (EOL) notices or Last-Time-Buy recommendations before finalizing procurement plans. Ensure compatibility with existing PCB footprint designs for the 8-VDFN-EP package.

Selection Notes

Select this component when a non-synchronous buck solution is sufficient for the application's efficiency requirements. Consider the 3A current limit and 27V maximum input voltage constraints during circuit design. Evaluate thermal performance needs due to the absence of synchronous rectification at higher loads. Verify that the 370kHz switching frequency aligns with electromagnetic interference (EMI) constraints.

Part Context

The AOZ1212DI belongs to the EZBuck family of regulators designed for cost-sensitive applications. It serves as a non-synchronous alternative to more complex synchronous controllers. The part is manufactured by Alpha & Omega Semiconductor Inc., a provider of power management and discrete semiconductor solutions. This specific model focuses on simplicity and reliability for standard buck conversion tasks.
