The W15 and W25 Families of high efficiency DC/DC converters offer power levels of up to 15 & 25 Watt, respectively, which exceeds that of other bricks with the same Industry-Standard Pinouts,
while providing much smaller footprints. With a wide input voltage range and single and multi-outputs, ranging from 1.5 to 12 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 aluminum heat spreader design
achieves very efficient heat transfer with no hot spots. The use of patented design concepts facilitates maximum power delivered with the highest efficiency of up to 90%. 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.
