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
The TMR series is a range of miniature regulated 2 Watt DC/DC- converters in a SIL-
package. Requiring only 2cm
2
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.
