Overview
The AOZ1024DI is a synchronous buck regulator IC from Alpha & Omega Semiconductor's EZBuck series. It provides an adjustable output voltage ranging from 0.8V to 15V with a maximum continuous output current of 4A. The device operates with an input voltage range of 4.5V to 16V and features a fixed switching frequency of 500kHz. Packaged in an 8-VDFN exposed pad, it supports positive single-output configurations for efficient DC-DC conversion.
Feature Summary
- Integrated synchronous rectification for improved efficiency
- Fixed 500kHz switching frequency for compact external component sizing
- Adjustable output voltage starting at 0.8V reference
- EZBuck topology for simplified design implementation
Applications
- Point-of-load regulation for embedded systems
- Power supply stages for industrial equipment
- Voltage regulation for communication infrastructure
- Battery-powered device power management
Procurement Notes
Verify the exact suffix designation against official manufacturer documentation, as variations may indicate specific tape-and-reel quantities or environmental ratings. Confirm current availability status directly with Alpha & Omega Semiconductor or authorized distributors, as lead times and stock levels fluctuate based on production schedules and regional demand.
Selection Notes
Select this component when a compact synchronous solution is required for 4A loads within a 16V input limit. Ensure the thermal performance of the 8-VDFN package meets the application's heat dissipation requirements. Verify that the 500kHz frequency aligns with electromagnetic interference constraints and inductor size goals compared to lower-frequency alternatives.
Part Context
This part belongs to the EZBuck family of synchronous buck regulators designed for high-density power applications. It complements other variants like the AOZ1014DI by offering integrated high-side and low-side MOSFETs in a small footprint. The series targets applications requiring efficient step-down conversion with minimal external component count.
Replacement Considerations
The AOZ1014DI serves as a higher-current alternative within the same EZBuck family, providing 5A output capability. Designers should verify pin compatibility and thermal characteristics when substituting between these models to ensure proper circuit integration.
