In the sense "produce by writing", this term is generally used only when the thing being written has been previously set or arranged to some extent. Thus, one can write up a report of events, minutes of a meeting, or a contract previously agreed upon orally.
As with many pairs of phrasal verbs that contain antonymic particles (such as up and down), write up and write down can actually function as synonyms for some senses.
