The TEL-2 series, comprising 28 models, is a range of isolated 2 Watt converters in
a low profile DIP-16 package. Requiring only 3.25 cm2 of space on the PCB they
provide a complete DC/DC converter without need of any external components.
Wide input range and tightly regulated output voltage qualifies these converters for
many cost critical applications in industrial and consumer electronics.
