The U15 Family of high efficiency DC/DC converters offer power levels of up to 15 Watt. With ultra-wide input voltage range and single and multi-outputs, these converters provide versatility without
sacrificing the board space. All models feature an input Pi filter and continuous short circuit protection. The fully enclosed, encapsulated construction achieves very efficient heat transfer with no hot
spots. All converters combine creative design practices with highly derated power devices to achieve very high reliability, high performance and low cost solution to systems designers.

The output voltage can be trimmed (±10%) using an external resistor. To trim the output up (down) connect a resistor between
pins 5 and 6 (7). A 10KΩ trim pot can also be used to make the output variable. Connect the wiper to pin 5 and make the other
connections to pins 6 and 7.
