Apparatus and method for DC/DC converter having high speed and accuracy
Patent No. 6,760,238
Issued: July 6, 2004
Inventor: Charych; Arthur (Setauket, NY)
Assignee:BC Systems, Inc (Setauket, NY)
A system and method for DC/DC conversion are provided in which a high accuracy digital pulse width modulator controller circuit controls a power switch to obtain a desired DC output. The control circuit amplifies the difference of a DC output sample in relation to voltage reference. The amplified difference is then compared with a portion of the DC output. The compared result is used for controlling the power switch. A ripple coming from the DC output side is overlaid upon either one of the inputs to the comparator depending upon the polarity of the ripple signal.
