DESCRIPTION

The MSKUW series of DC/DC converters provide a maximum of 5 watts in a “gull-wing” SMT

package. These converters operate over 4:1 ultra wide input voltage ranges of 9-36 or

18-75VDC. This series also has single output voltages of 3.3, 5, 12, and 15VDC and

dual output voltages of ±5, ±12, and ±15VDC. These converters have a typical full load

efficiency of 83%, remote ON/OFF control, and continuous short circuit protection. The

-40°C~+71°C operating temperature make these converters ideal for data communication

equipment, mobile battery driven equipment, process/machine control equipment,

telecommunication equipment, computer peripheral systems, distributed power systems, mixed analog/digital

subsystems, and industrial robot systems. The EN55022 Class A conducted noise compliance minimizes

design time, cost, and eliminates the need for external filter components.
