CS5171EDR8G is a power switching regulator IC from ON Semiconductor, designed to operate in Buck, Boost, Flyback, Forward Converter, and SEPIC configurations. This SoC is typically used to convert an unregulated input voltage to a regulated voltage output at positive or negative adjustment. The voltage output can be adjusted from 0.8V to 1.28V with 1.5A (switch) current and 8-SOIC packaging (0.154", 3.90mm width). The IC provides tight regulation under light load conditions, current limitation, and other protection features to enhance system reliability. The IC operates over a wide input voltage range of 4.5V to 40V, allowing it to be used in a variety of applications.
