DESCRIPTION

The MSKW series of DC/DC converters provide a maximum of 5 watts in a

“gull-wing” SMT package. These converters operate over 2:1 wide input

voltage ranges of 9-18, 18-36, or 36-75VDC. 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

85%, remote ON/OFF, 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.
