SVLTR5005DF/K Image

The SVLTR5005DF/K from VPT is a Space Qualified Buck DC-DC Converter that converts an input voltage of 30 - 60 V to an output voltage of 5 V. This DC-DC converter delivers an output power of up to 30 W and has an efficiency of 80%. It has been designed for use in harsh environments in space applications. This converter guarantees reliable performance through the use of hardened semiconductor components, radiation lot acceptance testing (RLAT) of non-hardened components, and analysis. It has also been characterized for robust total ionizing done (TID) performance including enhanced low dose rate sensitivity (ELDRS) and single event effects (SEE) as per MIL-PRF-38534, Appendix G, Level L standards.

This buck DC-DC converter integrates a proprietary radiation-immune feedback circuit that provides bias voltage to all the secondary control circuits and control amplifiers before the start of the output, thereby ensuring a well-controlled start-up sequence. It includes under voltage lockout (UVLO), current limit protection, and short-circuit protection (SCP) to prevent false triggers and over-current-related damages. This DC-DC converter is available in a seam-welded, hermetically-sealed flange-mount package that measures 2.890 x 1.125 x 0.405 inches and is ideal for launch vehicle programs, low earth orbit (LEO), medium earth orbit (MEO), geostationary orbit (GEO), and deep space applications.
