May 5, 2014—Polytron Devices, Inc. has recently released for mass production a complete line of 3 Watt DC/DC converters in a SIP package (0.86” X 0.36” X 0.44”) This “SWB3” series boasts high efficiency of 82% and on/off control flexibility. These converters are encapsulated and operate without de-rating over their full specified temperature range.
This series is available with a 4:1 input voltage range as follows: 9-36Vdc and 18-72Vdc. Single and Dual output voltages are available as follows: 3.3, 5, 9, 12, ±5, ±12, ±15Vdc.
Pertinent specifications include: continuous short circuit protection and 1600Vdc Isolation. These units are designed for a variety of applications including : wireless network, telecom/datacom, industry control system, measurement and semiconductor equipment. All units are 100% burned in under full load, hi pot tested and final electrical tested prior to shipment.
This series of converters is competitively priced at $19.75 at 1000 quantity. Average lead time is 4-5 weeks.
