Overview
The AOZ1024DI is a synchronous buck regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It operates with an input voltage range of 4.5V to 16V and provides a single adjustable output up to 16V. The device delivers a continuous output current of 4A at a switching frequency of 500kHz. It features a compact 8-DFN (4x5mm) package with an exposed pad for thermal management, suitable for surface mount installation.
Feature Summary
- Integrated synchronous rectification for high efficiency
- Fixed internal switching frequency simplifies external component selection
- Adjustable output voltage via external resistor divider
- Compact footprint optimized for space-constrained designs
Applications
- Point-of-load regulation for embedded systems
- Power supply stages in industrial equipment
- Voltage conversion for communication infrastructure
- Battery-powered device power management
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.
Selection Notes
Select this component when a 4A output current is required within a 16V input limit. The fixed 500kHz frequency reduces passive component size compared to lower-frequency alternatives. Consider the 8-DFN package thermal performance for your PCB layout. Verify that the adjustable output range meets the target load voltage requirements.
Part Context
This part belongs to the EZBuck family of synchronous buck regulators designed for efficient DC-DC conversion. It complements other variants like the AOZ1034 or AOZ1052 which offer different current ratings or input ranges. The series targets applications requiring reliable power delivery in compact form factors.
Replacement Considerations
Check for direct pin-compatible substitutes within the same EZBuck family. Verify if higher current variants like the AOZ1036DI meet thermal constraints. Ensure any replacement maintains the 500kHz switching frequency to preserve existing filter component values.
