SMAKN DC-DC Synchronous rectification buck Supply power module 16-40V To 1.0v-12v This products has the advaced synchronous recrification controller and 3.7 milliohm low impedance NMOS switch tube. those magical parts constitute this big current and high efficency DC-DC buck voltage converter. So it can work continuous in output current 6A without strong heat sink. If you can strength ventilation and heat dissipation, it can work above output current 8A for a long time. Input voltage: 16-40V(24V is the perfect voltage) Output voltage: 1.0v-12v Output current: 6A(natural heat dissipation) The load starting current: Rated 6A, Max 7A
