The SD8583S with Switching Controllers SOP-7-225-1.27 RoHS is a digital power controller IC from chip maker Silan Microelectronics. It is designed to provide a high-performance, cost-effective solution for advanced DC/DC switching power supply designs. It is used to control the output voltage levels and reduce power losses during switching of voltage levels. It features an on-board switching frequency of 1MHz, and is designed to achieve up to 97% of efficiency without additional components. It also features an adjustable current limit to increase system protection and provides a range of safety features including over voltage protection, over current protection, and auto recovery short circuit protection. The SD8583S is available in a 1.27mm pitch SOP package and is RoHS compliant.
