ST1S41PUR Description

Short technical summary and product information.

The STMicroelectronics ST1S41PUR is a buck topology switching voltage regulator with an adjustable output voltage. It is designed to handle an input voltage range from 4V to 18V and can deliver up to 4A of output current. The device operates at a switching frequency of 850kHz, making it suitable for various power management applications.

 

This regulator features a synchronous rectifier for improved efficiency. It is available in a surface mountable 8-VDFN exposed pad package, specifically an 8-DFN (4x4) size, facilitating integration into compact electronic designs. The operating temperature range is from -40°C to 150°C (TJ).

 

Key electrical characteristics include its 4V minimum input voltage and 18V maximum input voltage, with an adjustable output. The 4A current rating makes it suitable for power-hungry applications. Its step-down (buck) function and synchronous rectification contribute to efficient power conversion.

 

The ST1S41PUR is supplied on a reel, indicating suitability for automated assembly processes. Its compact package and robust operating temperature range make it a versatile component for embedded systems and power supply designs.
