Latest Updated:12/01/2011


At the beginning of the uPC1909 Data Sheet, there is a sentence that goes, "It is necessary to obtain license from Vicor Corporation before using the uPC1909 in an active-clamp type circuit."
What is the patent number?


The patent number of active clamp is "USP No.4,441,146".
It seems that Vicor call it Reset Patent.
For details, see the home page of Vicor.

Note that negotiations concerning use of the patent should be directly made between Vicor and the customer, and that NEC has nothing to do with such negotiations.
