Application No. 08/848,842
circuit tends to operate in equilibrium. By having the
capability to adjust the set point of the output voltage
signal level, the output voltage signal may be set within a
predetermined window at a voltage signal level providing
additional voltage margin to respond to an increase in load,
if one should occur. With this additional voltage margin,
less capacitance may be employed because the additional
voltage margin may be employed to at least partially offset
the transient voltage signal. A further understanding of the
invention can be obtained by the following claim.
1. A DC-to-DC converter circuit comprising: a circuit
configuration to modify the set point of the output voltage
signal of the DC-to-DC converter circuit in response to a
transient signal by an amount related, at least in part, to
the magnitude of the transient signal.

2The examiner lists two other patents, U.S. patent No.
4,618,812 to Kawakami and U.S. patent No. 4,161,023 to Goffeau
as part of the prior art of record on page 3 of the examiner’s
answer. However, these two patents do not form part of the
rejection before us. Therefore, we do not consider Kawakami
and Goffeau in our deliberations for this decision.
