| DC/DC Converters TMR Series, 2 Watt Features 2 Watt in SIL Package Regulated Output Wide 2 : 1 Input Range No external Capacitors needed Low Ripple and Noise Indefinite Short-Circuit Protection External On/Off - Control Lead free Design, RoHS compliant 3 Year Product Warranty compliant RoHS The TMR series is a range of miniature regulated 2 Watt DC/DC- converters in a SILpackage. 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 -40C - 75C with no derating makes this converter suitable for many applications in telecommunication, control units and industrial equipments.
