U3-12S3.3

U3 SERIES DC/DC MODULES Specifications & Features Summary • Servers, Switches and Data Storage • Wireless Communications • Distributed Power Architecture • Semiconductor Test Equipment Applications • Networking Gear • Data Communications • Telecommunications • 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. • Regulated Outputs • 5-sided metal shield High Isolation versions • -25°C to +71°C ambient operation • 200KHz Switching Frequency • Continuous Short-circuit protection • up to 3KV, 10MΩ input-to-output isolation • No airflow or heatsink required • Voltage Accuracy ± 2% • Pi Input Filter • 4:1 Input Range • THROUGH-HOLE PACKAGES ONLY Model Num U3-12S5 U3-12S12 U3-12S15 U3-12D5 U3-12D12 U3-12D15 U3-12S3.3 U3-48S5 U3-48S12 U3-48S15 U3-48D5 U3-48D12 U3-48D15 U3-48S3.3 VIn 9-36 VDC 9-36 VDC 9-36 VDC 9-36 VDC 9-36 VDC 9-36 VDC 9-36 VDC 18-72 VDC 18-72 VDC 18-72 VDC 18-72 VDC 18-72 VDC 18-72 VDC 18-72 VDC VOut 5.0 VDC 12.0 VDC 15.0 VDC ±5.0 VDC ±12.0 VDC ±15.0 VDC 3.3 VDC 5.0 VDC 12.0 VDC 15.0 VDC ±5.0 VDC ±12.0 VDC ±15.0 VDC 3.3 VDC IOut 600.0 mA 250.0 mA 200.0 mA ±300.0 mA ±125.0 mA ±100.0 mA 600.0 mA 600.0 mA 250.0 mA 200.0 mA ±300.0 mA ±125.0 mA ±100.0 mA 600.0 mA INo Load 15.0 mA 15.0 mA 15.0 mA 25.0 mA 25.0 mA 25.0 mA 15.0 mA 7.5 mA 7.5 mA 7.5 mA 12.0 mA 12.0 mA 12.0 mA 7.5 mA IFull Load 174 mA 165 mA 165 mA 179 mA 174 mA 174 mA 117 mA 87 mA 78 mA 78 mA 88 mA 87 mA 87 mA 58 mA Eff 72% 76% 76% 70% 72% 72% 70% 72% 80% 80% 71% 72% 72% 70% Case T T T T T T T T T T T T T T Approval Pending SPECIFICATIONS Input Specifications Input Voltage Range 24V--------9-36V 48V--------18-72V Pi Type ±2.0% max. ±1.0% / max. ±0.05% / oC 100mV p-p max. 1% p-p max.
