ST1S40IPUR Description

Short technical summary and product information.

The STMicroelectronics ST1S40IPUR is a Power Management Integrated Circuit (PMIC) designed as a DC-DC Step-Down Regulator. It offers an adjustable output voltage and can handle a maximum output current of 3A, with a peak capability of 4A. The device operates with an input voltage range from 4V to 18V and features a maximum switching frequency of 850kHz.

 

This regulator is suitable for surface mount applications, utilizing an 8-VFQFPN (4x4) package. It includes a synchronous rectifier for improved efficiency. The operating temperature range is from -40°C to 150°C (TJ).

 

Key electrical characteristics include a minimum output voltage of 0.8V and a maximum output voltage of 18V. The device is designed for positive output configurations and functions as a buck converter.

 

Compliance information indicates RoHS3 compliance and a Moisture Sensitivity Level (MSL) of 1 Unlimited. The component is also designated as Lead Free.
