The U20 Families of high efficiency DC/DC converters offer power levels of up to 20 Watt, which exceeds that of other bricks with the same Industry-Standard Pinouts, while providing much smaller
footprints. With a ultra- wide input voltage range and single and multi-outputs, ranging from 3.3 to ±15 Volts, these converters provide versatility without sacrificing the board space. All models
feature an input filter, input undervoltage lockout, output current limiting and 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.
