Description
The Z1051PI is a high efficiency, easy to use, 3 A synchronous buck regulator. The AOZ1051PI works from 4.5 V to 18 V input voltage range, and provides up to 3 A of continuous output current with an output voltage adjustable down to 0.8 V.
A synchronous buck regulator is a type of DC-DC (direct current to direct current) power converter that is commonly used to step down a higher voltage input to a lower voltage output.
The synchronous buck regulator is known for its high efficiency, due in part to the synchronous switching technology that minimizes power losses. It is widely used in electronic devices such as computers, smartphones, and other battery-powered applications where efficient power conversion is critical.
