Cxlb74169 is a step-down converter integrated with synchronous switch supporting DCP output protocol providing a complete solution for car charger, adapter intelligent plug-in

Cxlb74169 is a step-down converter integrated with synchronous switch, supporting DCP (bc1.2, apple2.4a, Samsung) output protocol, providing a complete solution for car charger, adapter, intelligent plug-in, dash cam. Cxlb74169 has built-in power MOS, the input voltage range is 8V to 32V, and the output voltage is 5V. The maximum output current is 2.4a. The step-down conversion efficiency of cxlb74169 is as high as 94%. The output of cxlb74169 has the characteristics of CV / cc. When the output current is less than the set value, the output CV mode has a constant output voltage; when the output current is greater than the set value, the output CC mode has a reduced output voltage. The output voltage of cxlb74169 has the function of wire compensation.
