STMicroelectronics ST1S31D-R is a high-frequency synchronous buck switching regulator designed for efficient step-down voltage conversion. This adjustable output regulator supports a minimum output voltage of 0.8V and can deliver up to 3A of output current. Operating with an input voltage range of 2.8V to 5.5V, it features a high switching frequency of 1.5MHz, enabling the use of smaller external components and reducing overall solution size. The ST1S31D-R is housed in an 8-SOIC package with a 3.90mm width, suitable for surface mount applications. Its internal synchronous rectifier enhances efficiency. This component is commonly utilized in power management solutions for consumer electronics, industrial automation, and automotive applications.
