The SA50-120-28S-A-H from Microchip Technology is a DC to DC Converter that converts a DC input voltage of 120 V and a DC output voltage of 28 V. This radiation-hardened converter delivers an output power of up to 50 W and has an efficiency of up to 85% at full load conditions. It has a ripple voltage range of 100-280 mVpp and an output current of 1.8 A. This isolated DC-DC converter is based on forward converter topology and features patented magnetic feedback. It has a line regulation of 56 mV and a load regulation of 280 mV. The converter has a MIL-STD-461-compliant internal EMI filter and consists of differential and common mode components to attenuate conductive EMI noise effectively. It has a radiation tolerance TID of greater than 100 krad (Si) and a SEE immunity of 82 MeV·cm2/mg. The converter has a low mass of 120 g and measures 3.055 x 2.055 x 0.5 inches. It is based on flight-proven technology with a high MTBF and is ideal for space and military applications.
