ALISO VIEJO, Calif., 19 April 2012. Microsemi Corp. in Aliso Viejo, Calif., is introducing the SA50-28 family of radiation-hardened single-, dual-, and triple-output DC-DC converters for military and commercial satellites that require protection against naturally occurring total-dose ionized radiation, which can hurt system performance.
The 50-Watt Microsemi (Nasdaq: MSCC) rad-hard power supplies come in surface-mount packaging and have 28-volt input. The SA50-28 power electronics devices enable designers to make the most of board real estate because their packaging and weight density are similar to hybrid alternatives, Microsemi officials say.
Microsemi's rad-hard DC-DC converters have an isolated power supply that can drive point-of-load (POL) converters, which help step down power to devices like customizable system-on-chip (cSoC) and field programmable gate arrays (FPGAs). The power supplies also have an isolated synchronization scheme to manage system noise spectra.
Microsemi qualified space products include converters, customizable system-on-chip solutions, MOSFETs, rectifiers, switching diodes, transistors and zeners in standard and customized space versions.
