LSO2801R5S Datasheet | IRF

Description The LSO Series of DC-DC converters are, high reliability devices designed for hostile radiation hardened environments. The design is based on the heritage-rich LS Series with enhanced functional performance and an inclusion of an output overvoltage protection. The LSO Series provide up to 30 watts output power, small size, low weight, integrated EMI filtering and a high tolerance to environmental stresses such as radiation, temperature extremes, mechanical shock, and vibration. All ponents are fully de-rated to meet the requirements of MIL-STD-1547, MIL-STD-975 and NASA EEE-INST002. Extensive documentation including, thermal analysis, stress analysis and reliability predictions are available. The LSO Series of converters incorporate a fixed frequency single forward topology with magnetic feedback and an internal EMI filter. These converters are capable of meeting the conducted emissions requirements of MIL-STD-461C without any additional ponents. All models include an external inhibit port and have an adjustable output voltage. The converters are overload, short circuit and output over-voltage protected. They are enclosed in a hermetic 3.5" x 2.5" x 0.475" H steel package and weigh less than 125 grams. The package utilizes rugged ceramic feed-through copper core pins and is sealed using parallel seam welding. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are fabricated utilizing DLA qualified processes. For available screening options, refer to device screening table in the data sheet. Variations in electrical specifications and screening to meet custom requirements can be acmodated.
