Appeal No. 1999-1992
Application No. 08/848,842
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-10, 12-19, and 22. Claims1
11, 20, and 21 have been canceled.
The invention is directed to a Direct-Current (DC) to
Direct-Current (DC) converters. They are typically employed
to convert from one DC voltage signal level to another DC
voltage signal level. One situation that is frequently an
issue with such converters occurs when a sizable load is
applied to the converter. A relatively sudden increase in
load may be approximated as a step function and, as is well-
known, typically results in a transient voltage signal in the
circuitry to which the step function is applied. Such
transients are undesirable because one of the functions of a
DC-to-DC converter is to maintain an output voltage signal
level within a particular voltage signal window or a set of
voltage signal boundaries to ensure, for example, that the
operation of the circuitry being powered by the DC-to-DC
converter is not substantially affected by the sudden increase
1An amendment after final rejection was filed as Paper
No. 11, the examiner approved its entry, see Paper No. 12.
However, we note that the amendment has not been physically
entered into the record. We refer this matter to the
examiner, to ensure entry of the amendment.
