DC/DC Converters
TEM 2 Series, 2 Watt
The TEM 2 series is a family of isolated dc/dc converters in a DIP-24 package. They
offer tight line/load regulation and 1000 VDC I/O isolation. Standard features in-
clude an internal filter to reduce reflected input ripple currrent and to guarantee low
output noise. This product series provides a cost effective solution by many industrial
or consumer electronics appliactions.
