RT6219AGQW Description

Short technical summary and product information.

The RT6219AGQW is a step-down (buck) switching regulator from RICHTEK designed for high-efficiency power conversion. It features a synchronous rectifier topology and operates at a fixed switching frequency of 500kHz. The device accepts an input voltage range of 5V to 23V and provides a single adjustable output from 0.6V to 5V with a maximum output current of 4A.

 

This regulator is housed in a compact 10-WFDFN exposed pad package (10-WDFN 3x3mm) suitable for surface mount assembly. It is rated for an operating temperature range of -40°C to 85°C, making it suitable for industrial and commercial environments. The synchronous rectifier design improves efficiency by reducing external diode losses.

 

The RT6219AGQW is ideal for applications requiring a high-current, adjustable output voltage from a moderate input supply. Its small package and high switching frequency allow for compact power supply designs with minimal external components.
