The XCL201B181ER-G is an inductor micro DCDC Converter manufactured by Torex Semiconductor that has a switching voltage regulator for output current of up to 400mA. The device is housed in a compact 8-pin, thermally enhanced, SOP-8 package, and its wide input voltage range of 2.4V to 5.5V and excellent power conversion efficiency provides greater design flexibility. The integrated low-side MOSFET(LSM) gives designers the option of operating the device without an external MOSFET, and its programmable soft-start feature helps to reduce inrush current. This product is designed for a wide range of applications, including portable electronics, automotive, industrial, communications, and wireless products.
