The AOZ2261BQI-20 from Alpha & Omega Semiconductor is a robust synchronous step-down (Buck) DC-DC converter designed for high-current, wide-input-voltage applications. It accepts an input from 10V to 28V and delivers up to 8A of output current with an adjustable output from 0.8V to 5V. The 1MHz switching frequency provides a good balance between efficiency and component size. Housed in a 22-PowerVFQFN package, it is well-suited for industrial, telecom, and automotive systems requiring reliable high-current conversion.
- High Current Capacity: 8A output supports demanding industrial and telecom loads.
- Wide Input Voltage: 10V to 28V covers 12V and 24V systems.
- High Efficiency: Synchronous design minimizes heat generation at high currents.
- Compact Power Package: PowerVFQFN enhances thermal dissipation and reduces footprint.
Industrial Power Supplies
With 10V to 28V input and 8A output, it powers industrial control systems, PLCs, and motor drivers from 12V or 24V rails.
Telecom and Networking
It provides efficient point-of-load conversion for base stations, switches, and routers, handling high current demands from 24V backplanes.
Automotive Infotainment
