• Wireless Communications
• Data Communications
• Distributed Power Architecture
• Telecommunications
• Semiconductor Test Equipment
• Industrial / Medical
The U3 Family of high efficiency DC/DC converters offer power levels of up to 3 Watt, which exceeds that of other sub-bricks with the same package, while also providing Ultra-Wide Input Voltage
Range. With a 4:1 input voltage range and single & multi-outputs, these converters provide versatility without sacrificing the board space. All models feature an input filter, continuous short circuit
protection and regulated outputs. The fully enclosed, encapsulated construction facilitates maximum power delivered with the highest efficiency of up to 80%. 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.
Specifications & Features Summary
• Regulated Outputs
• -25°C to +71°C ambient operation
