The Alpha & Omega Semiconductor AOZ2140DI is a synchronous buck DC-DC converter designed for high-efficiency power conversion. It operates from 3V to 5.5V input and provides an adjustable output from 0.8V to 4.67V, with current ratings up to 3A or 5A. The fixed 650kHz switching frequency offers a good balance between efficiency and component size. Housed in a 14-WFDFN package with exposed pad, it is ideal for computing, networking, and industrial applications.
- High Output Current: Supports up to 5A, suitable for demanding processor and ASIC loads.
- Wide Output Range: 0.8V to 4.67V covers common logic and I/O voltages.
- Efficient Operation: Synchronous rectification minimizes power loss at high currents.
- Robust Thermal Design: Exposed pad package enhances heat dissipation for reliable operation.
High-Current Point-of-Load
With up to 5A output capability, the AOZ2140DI is suitable for powering high-performance processors, GPUs, and FPGAs from a 5V rail in computing systems.
Base Stations and Routers
