DESCRIPTION
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 EUP2570 integrated multiple protections, such as OC, UVLO, OT, OVP, which will prevent damage in the event of an output overload. The EUP2570 is available in the tiny SOT23-5 package to provide the best solution for PCB space saving and total BOM cost. FEATURES
