The TMR series is a range of miniature regulated 2 Watt DC/DC- converters in a SIL-
package. Requiring only 2cm2 board space they provide a state of art functionality.
Wide 2:1 Input voltage range, 1000 VDC isolation voltage, external on/off control
and a temperature range of -40°C 7C with no derating makes this converter
suitable for many applications in telecommunication, control units and industrial
equipments.
