The 50-W GH series of radiation hardened dc/dc converters target spacecraft applications that require mission life up to 15 years. The converter suits designs with new digital signal processors and FPGA technologies that require a supply voltage as low as 1.0 V. It features an 18 to 40-V input range, 100-krad total ionization dose, rated linear energy transfer >82 MeVcm2 /mg, an internal EMI filter complying with most major satellite power buses, and a weight of less than 110 g.
The dc/dc converter features an output range from 1.0 to 5.0 V with a current rating up to 20 A, and 87% efficiency. The output voltage is adjustable with an external resistor with an adjustment range of ±10%. Other key features include remote sense compensation, remote output on/off control via the inhibit pin, input under-voltage protection with under-voltage lockout, and synchronization for applications with multiple converters.
