VR-78H Series
0.4A - 0.5A Output Current, Non-Isolated DC/DC converter
The VR-78H series is a family of cost effective 1.65 ~ 6W single output buck DC-DC converters. These converters are encapsulated in a non-conductive black plastic package 3-pin SIL case, continuous short circuit 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, and 21 ~ 72 with output voltage of 3.3, 5, 6.5, 7.2, 9 , 12 and 15 VDC. High performance features include high efficiency operation up to 95%.
