These converters are encapsulated in a non conductive black plastic 3-pin SIP case, continuous short circ uit protection with automatic restart, good line / load regulation and ultra low quiescence current. Devices are filled up with flame retardant resin .Input voltages of 9~72, 14~72, 17~72, 20~72, and 36~72 with output vo ltage of 3.3, 5, 6.5, 7.2, 9 , 12 and 15Vdc. High performance features in clude high efficiency operation up to 95%.
