RT7257ALZSP Description

Short technical summary and product information.

The RICHTEK RT7257ALZSP is a step-down (buck) DC-DC switching regulator designed for power management applications. It features an adjustable output voltage that can be set between 0.8V and 15V, with a maximum output current capability of 3A. The device operates from an input voltage range of 4.5V to 18V and has a switching frequency of 340kHz.

 

This regulator is housed in an 8-SOIC package with an exposed pad for enhanced thermal performance, suitable for surface mount applications. The operating temperature range is -40°C to 85°C (TA). Its adjustable output and high current capability make it suitable for various power supply designs requiring efficient voltage conversion.

 

Key electrical specifications include a minimum input voltage of 4.5V and a maximum of 18V, with an adjustable output voltage from 0.8V up to 15V. The synchronous rectifier feature contributes to improved efficiency. The component is designed for positive output configuration and is a single-output device.
