The CXSU63186 switching regulator is a current-mode boost converter operating at fixed frequency of 1MHz. It is designed for small LCD bias supply and others micropower step-up applications. The 18V switch allows for output voltage as high as 17V. The integrated 0.19Ω power switch and 2A current limit will provide high efficiency over a wide range of load conditions with high power density. The CXSU63186 integrated multiple protections, such as OC, UVLO, OT, OVP, which will prevent damage in the event of an output overload. The CXSU63186 is available in the tiny SOT23-5 package to provide the best solution for PCB space saving and total BOM cost.
