The document describes a high reliability, radiation tolerant DC/DC converter designed for moderate radiation environments such as low earth orbit satellites and launch vehicles. The converters are characterized by small size, low weight, high radiation tolerance, and resistance to environmental stresses.
The L‑Series DC/DC converters are radiation‑tolerant, high‑reliability devices intended for low‑earth‑orbit satellites and launch vehicles. They feature a compact steel package, magnetic feedback, internal EMI filtering, and an external inhibit port. All models provide adjustable output voltage, overload protection, and meet MIL‑STD‑461C emissions requirements.
The manual includes circuit descriptions, electrical performance tables, radiation test results, mechanical diagrams, and block diagrams for both single‑output and dual‑output configurations. It also outlines design methodology, environmental screening procedures, and application notes for space systems.
