VPT radiation-hardened DC-DC converters for space environments provide wide input voltage range

BLACKSBURG, Va. Radiation-hardened SVR Series isolated DC-DC converters from VPT Inc., a HEICO company (NYSE:HEI.A; NYSE:HEI), now offer an 18-volt to 40-volt input range to meet the needs of electronics systems in space environments. “The demands of the space market continue to expand and change,” says Monty Pyle, vice president of sales and marketing for VPT. “Now more customers are seeking rad-hard solutions that require up to 40 V input, without the need to meet the stringent Aerospace TOR and MIL-HBK-1547 derating requirements.

“The demands of the space market continue to expand and change,” says Monty Pyle, vice president of sales and marketing for VPT. “Now more customers are seeking rad-hard solutions that require up to 40 V input, without the need to meet the stringent Aerospace TOR and MIL-HBK-1547 derating requirements.

“Since our SVR Series is MIL-PRF-38534 Class H and Class K qualified and available on DLA Standard Microcircuit Drawings (SMDs), the products offer the ideal efficiency and reliability for such customers,” Pyle adds. Although the SVR Series isolated converters have always had 18 to 40 V range operation, he says, the products were initially specified at 37.5 volts to support Aerospace TOR and MIL-HBK-1547 requirements, for which the SVR Series was originally developed.

SVR Series DC-DC converters, in single- and dual-output versions, has been characterized to 100 krad(Si) Total Ionizing Dose (TID), including Enhanced Low Dose Rate Sensitivity (ELDRS), and Single Event Effects (SEE) performance to 85 MeV-cm2/mg.

All SVR Series isolated DC-DC converters from VPT feature a wide input voltage range of 18 to 40, with a 50 V transient operation. The SVR Series isolated converters are highly efficient and utilize VPT’s proprietary radiation immune magnetic feedback technology. Features of the series include input undervoltage lockout, output soft start, current limit and short circuit protection. Additionally, the SVR Series is rated for full power operation up to 125° C.

The first standard commercially available products from VPT were designed specifically for the harsh environment of space. Now with nearly 25 years of proven space heritage, VPT offers high-reliability and high-efficiency solutions to organizations around the world in industries which require reliable operation of each component for overall mission success.

VPT, Inc., part of the HEICO Electronic Technologies Group, is a global provider of DC-DC power converters, EMI filters, and custom engineering services for avionics, military, space, and industrial applications. Every day, organizations like NASA, ESA, Lockheed Martin, Boeing, BAE Systems, Thales, and many more depend on high-reliability solutions from VPT to power critical systems.

HEICO Corporation (NYSE:HEI.A) (NYSE:HEI) is engaged primarily in niche segments of the aviation, defense, space and electronics industries through its Hollywood, Fla.-based HEICO Aerospace Holdings Corp. subsidiary and its Miami, FL-based HEICO Electronic Technologies Corp. subsidiary.
