W3-12S15

W3 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 W5 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 Surface Mount Processable construction. With a wide input voltage range and single and 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 83%. 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 • -25°C to +71°C ambient operation • 100KHz Switching Frequency • Continuous Short-circuit protection Approval Pending • up to 3KV, 10MΩ input-to-output isolation • No airflow or heatsink required (W7 Model Shown) • Voltage Accuracy ± 2% • Pi Input Filter • Delivers up to 5W in 1”x1.25”x0.45” package with Industry-Standard SMD Pinouts • 2:1 Input Range • THROUGH-HOLE PACKAGES AVAILABLE (add suffix “T” to the part number) Model Num W3-12S5 W3-12S12 W3-12S15 W3-12D12 W3-12D15 W3-12D5 W3-12S3.3 W3-24S5 W3-24S12 W3-24S15 W3-24D12 W3-24D15 W3-24D5 W3-24S3.3 W3-48S5 W3-48S12 W3-48S15 W3-48D12 W3-48D15 W3-48D5 W3-48S3.3 VIn 9-18 VDC 9-18 VDC 9-18 VDC 9-18 VDC 9-18 VDC 9-18 VDC 9-18 VDC 18-36 VDC 18-36 VDC 18-36 VDC 18-36 VDC 18-36 VDC 18-36 VDC 18-36 VDC 36-72 VDC 36-72 VDC 36-72 VDC 36-72 VDC 36-72 VDC 36-72 VDC 36-72 VDC VOut 5.0 VDC 12.0 VDC 15.0 VDC ±12.0 VDC ±15.0 VDC ±5.0 VDC 3.3 VDC 5.0 VDC 12.0 VDC 15.0 VDC ±12.0 VDC ±15.0 VDC ±5.0 VDC 3.3 VDC 5.0 VDC 12.0 VDC 15.0 VDC ±12.0 VDC ±15.0 VDC ±5.0 VDC 3.3 VDC IOut 600.0 mA 250.0 mA 200.0 mA ±125.0 mA ±100.0 mA ±300.0 mA 600.0 mA 600.0 mA 250.0 mA 200.0 mA ±125.0 mA ±100.0 mA ±300.0 mA 600.0 mA 600.0 mA 250.0 mA 200.0 mA ±125.0 mA ±100.0 mA ±300.0 mA 600.0 mA INo Load 7.5 mA 7.5 mA 7.5 mA 12.0 mA 12.0 mA 12.0 mA 7.5 mA 5.0 mA 5.0 mA 5.0 mA 7.5 mA 7.5 mA 7.5 mA 5.0 mA 2.0 mA 2.0 mA 2.0 mA 3.0 mA 3.0 mA 3.0 mA 2.0 mA IFull Load 545.0 mA 585.0 mA 625.0 mA 575.0 mA 590.0 mA 545.0 mA 393.0 mA 265.0 mA 285.0 mA 305.0 mA 285.0 mA 295.0 mA 265.0 mA 197.0 mA 133.0 mA 145.0 mA 154.0 mA 142.0 mA 147.0 mA 133.0 mA 98.0 mA Eff 76% 80% 80% 80% 80% 76% 70% 78% 82% 82% 81% 81% 78% 70% 78% 81% 81% 81% 81% 78% 70% Case T T T T T T T T T T T T T T T T T T T T T SPECIFICATIONS Input Specifications Input Voltage Range 12V----------9-18V 24V--------18-36V 48V--------36-72V Pi Type +/-2.0% max. +/-1.0% / max. +/-0.05% / oC 3.3V / 5V----------100mV p-p max. 12V / 15V---------------1% p-p max.
