The ST1S09IPUR is a compact, synchronous buck regulator with a 2 A output current, designed for efficient power systems in mobile, industrial, and embedded applications. Integrated transistors and high switching frequency enable the design of miniature, low-noise converters with adjustable output voltage.
Description
Monolithic, synchronous step-down (buck) converter designed for high-efficiency power supply applications, offering adjustable output voltage and up to 2 A output current. Operates over an input voltage range from 2.7 V to 6 V, making it suitable for direct powering from battery systems or 5 V rails. Integrated MOSFET transistors and a 1.5 MHz switching frequency allow the use of miniature passive components, promoting compact system design. The regulator includes protection features such as short-circuit, thermal shutdown, and undervoltage lockout. Surface-mounted in a compact DFN-6 package.
