Minmax's MEW1000-Series power modules are low-profile dc-dc converters that operate over input voltage ranges of 9-36VDC and 18-75VDC which provide precisely regulated output voltages of 3.3V, 5V, 12V, 15V, {5V, {12V and {15VDC. The MEW1000 series is an excellent selection for data communication equipments, mobile battery driven equipments, distributed power systems, telecommunication equipments, mixed analog/digital subsystems, process/machine control equipments, computer peripheral systems and industrial robot systems. The modules have a maximum power rating of 2W and a typical full-load efficiency of 80%, continuous short circuit, 30mV output ripple, built-in filtering for both input and output minimize the need for external filtering.
