PD-97806 ML1000605D HIGH RELIABILITY RADIATION HARDENED LOW POWER DC-DC CONVERTER Description The ML-Series of isolated DC-DC converters for space applications are low power radiation hardened high reliability devices designed for hostile radiation environments such as those encountered by geostationary earth orbit satellites, deep space probes and communication systems. Features include small size, high efficiency, low weight, and a good tolerance to total ionizing dose, single event effects, and environmental stresses such as temperature extremes, mechanical shock, and vibration. All components are fully derated to meet the requirements of EEE-INST-002 (NASA) and ECSS-Q30-11A (ESA). Extensive documentation including worst case analysis, radiation susceptibility, thermal analysis, stress analysis, and reliability analysis are available. The ML-Series converter has two outputs – one positive and one negative - each is independently regulated via linear post regulators. The outputs are sequenced during turn-on and turn-off such that negative output comes up first at turn-on and stays up at turn-off until the positive output has decreased. The ML-series converters incorporate a fixed frequency flyback power converter and internal EMI filter that meets the requirements for most major satellite power buses. The converter includes isolated On/Off telecommand with associated status telemetry. The converter also includes input under voltage shut-down functionality. Due to the linea...
