Z1051PI PDF – 3A, Synchronous Buck Regulator ( AOZ1051PI )

A synchronous buck regulator, often simply called a “synchronous buck converter,” is a type of switching voltage regulator used to step down a higher input voltage to a lower output voltage efficiently. It’s a variation of the basic step-down or buck regulator that incorporates synchronous rectification to improve overall efficiency.

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.
