AOZ1021AI Description

Short technical summary and product information.

The AOZ1021AI-5L is a synchronous, high-efficiency buck regulator designed for step-down DC/DC conversion. It supports an input voltage range from 4.5V to 16V and can deliver up to 3A of continuous output current. The output voltage is adjustable, with a minimum setting of 0.8V.

 

This regulator features internal high-side (100mΩ) and low-side (20mΩ) switches, enabling high efficiency up to 95%. It operates at a fixed 500kHz PWM frequency. The device includes internal soft start, cycle-by-cycle current limit, pre-bias start-up, short-circuit protection, and thermal shutdown for robust operation.

 

The AOZ1021AI-5L is housed in a compact 8-SOIC package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). This component is suitable for point-of-load DC/DC conversion in various applications.
