DESCRIPTION
The WRA-YT-2W&WRB-YT-2W series is a family of high
performance 2W DC/DC converter modules featuring wide
2:1 input voltage ranges. The 28 models come in a low
profile SMD package which requires just 3 cm
2
space on
the PCB. A high efficiency allows an operating
temperature range of –40°C to 71°C without derating. A
built-in EMI input filter complies with EN 55022, class A.
Typical applications for these converters are battery
operated equipment, instrumentation, communication and
industrial electronics, everywhere where isolated, tightly
regulated voltages are required.
