AOZ1283PI

Overview

The AOZ1283PI is a high-voltage, high-efficiency buck regulator from the EZBuck™ series by Alpha & Omega Semiconductor. It operates within a 3.0V to 36V input voltage range and delivers up to 2.5A of continuous output current. The output voltage is adjustable from 0.8V to 30.6V. This device integrates an N-channel high-side power MOSFET and supports switching frequencies between 200kHz and 2MHz via an external resistor. It features adjustable soft-start time through an external capacitor and is housed in an 8-SOIC package with an exposed pad.

Feature Summary

Integrates an N-channel high-side power MOSFET for simplified design
Adjustable switching frequency allows optimization for size and efficiency
Configurable soft-start time reduces inrush current during startup

Applications

Point-of-load regulation for industrial systems
Power supply stages for computing equipment
Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix 'PI' corresponds to the 8-SOIC-EP package and tape-and-reel orientation as documented in the official datasheet. Confirm RoHS compliance status and manufacturing origin details against the latest product change notices issued by Alpha & Omega Semiconductor before finalizing procurement orders.

Selection Notes

Select this component when a single-output step-down converter is required with an input voltage up to 36V. It is suitable for designs needing up to 2.5A load current where adjustable output voltage and programmable switching frequency are necessary. Ensure thermal management accounts for the SOIC-EP package characteristics.

Part Context

The AOZ1283PI belongs to the EZBuck™ family of simple buck regulators designed by Alpha & Omega Semiconductor. This series focuses on high efficiency and ease of implementation for various power management applications. The PI suffix indicates the specific packaging and reel configuration for surface-mount assembly.
