The RT7263EZQW is a synchronous step-down voltage regulator capable of delivering up to 3A of continuous output current. It operates over a wide input voltage range of 4.5V to 21V and provides an adjustable output voltage from 0.808V to 15V. The device features a fixed switching frequency of 500kHz and supports external clock synchronization from 300kHz to 2MHz. Key protection features include cycle-by-cycle current limiting and thermal shutdown, ensuring safe operation under fault conditions. The adjustable soft-start function helps to minimize inrush current during startup. The RT7263EZQW is designed to require a minimal number of external components, making it suitable for compact applications. It is available in a WDFN-14L package with an exposed pad for enhanced thermal performance and is compliant with RoHS standards. This regulator is suitable for various applications, including distributed power systems, battery chargers, DSL modems, and as a pre-regulator for linear regulators.
