The TEN 8 series DC/DC converter has been designed for a wide
range of space critical applications including tele- and data communi-
cation systems and industrial process control systems. The shutdown
input feature makes these converters also ideal for mobile battery pow-
ered equipment. High efficiency allows operation up to 71°C without
derating. Input filtering to EN 55022, class A and low output ripple
minimize design-in time and cost.
