VPT Introduces SVRSA Series of 6W Output

Radiation Hardened DC-DC Converters



BLACKSBURG, VA, October 25, 2017 VPT, Inc. (VPT®), a HEICO company (NYSE:HEI.A) (NYSE:HEI), today released its single and dual output SVRSA DC-DC converters to further expand its offering of radiation hardened high-reliability space products. Specifically designed for the harsh radiation environment facing space applications, the SVRSA Series has been characterized to Total Ionizing Dose (TID) to 100 krad(Si), including Enhanced Low Dose Rate Sensitivity (ELDRS), and Single Event Effects (SEE) performance to 85 MeV-cm2/mg.

The SVRSA 6W output series offers a wide input voltage range of 18 to 40V, plus 50V transient operation, and is available in single output voltages of 3.3, 5, 12 and 15V and dual output voltages of ±5, ±12 and ±15V. The series topology is an isolated single-output flyback converter featuring VPT’s proprietary radiation immune magnetic feedback technology. Features of the SVRSA Series include input undervoltage lockout, output soft start, current limit and short circuit protection, and is rated for full power operation up to 125° C.


“We’ve leveraged our proven heritage in space product development in the design of the SVRSA Series, which follows our DLA-approved Radiation Hardness Assurance plan and is in accordance with Aerospace TOR requirements,” said Leonard Leslie, Vice President of Engineering for VPT. “This high efficiency hybrid series of DC-DC converters is aligned with programs headed for low Earth orbit or deep space.”


Comprehensive environmental screening for the SVRSA Series is per MIL-STD-883 as referenced in MIL-PRF-38534 including Class H and Class K. The DLA Land and Maritime has officially released the SVRSA Series standard microcircuit drawings (SMDs) under SMD family numbers 5962R15217 for the single output converters and 5962R15218 for the dual output converters.
