RT7231GQW Description

Short technical summary and product information.

The RT7231GQW is a synchronous buck (step-down) switching regulator designed for applications requiring up to 4A output current. The output voltage is adjustable from 0.765V to 8V, suitable for powering a wide range of loads. The input voltage range is 4.5V to 18V, making it compatible with common supply rails. The regulator operates at a fixed switching frequency of 650kHz, balancing efficiency and component size. Quiescent current is 1mA, aiding light-load efficiency. The operating temperature range is -40°C to +85°C, allowing use in industrial environments. The device is packaged in a 10-WFDFN with exposed pad, enabling effective thermal dissipation in surface-mount designs.
