Radiation-hardened DC-DC converters for low-voltage space microprocessor power applications offered by VPT
BLACKSBURG, Va. – VPT Inc., a HEICO company in Blacksburg, Va., is introducing the SVRPL series of space-qualified point-of-load DC-DC converters for space applications facing harsh radiation environments while requiring low voltages and tight regulation for high-performance processors.
These power electronics devices cover an input voltage range of 3.1 to 5.5 volts and are available in 6-amp output surface-mount options. The SVRPL3R306SG is based on the Intersil ISL70001ASEH radiation-hardened monolithic buck regulator. It is designed to operate from a nominal 3.3 volts or 5-volt bus.
The SVRPL3R306SG supplies low voltages at 6 amps with high efficiency, making it suitable to supply point-of-load applications such as high-performance space processors.
The series is characterized for total ionizing dose (TID) performance, including enhanced low dose rate sensitivity (ELDRS) and for single event effects (SEE) and is operable over the full military temperature range of -55 to 125 degrees Celsius with no power derating, and has been submitted for qualification to MIL-PRF-38534 Class H and Class K, and Radiation Hardness Assurance (RHA) Level R.
The availability of the SVRPL series is subject to all applicable U.S. export license restrictions and regulations. For more information contact VPT online at www.vptpower.com.
