发明名称 A POWER REGULATOR FOR DRIVING PULSE WIDTH MODULATOR
摘要 <p>A voltage regulator that modulates the switching of a switching circuit to regulate the output voltage level supplied to a system. The regulator uses a comparator circuit to compare a reference signal to an analog signal derived from the output voltage of the regulator, and outputs a binary signal based on the comparison. The regulator may use a counter circuit that interrogates the binary signal from the comparator circuit and generates a counter signal proportional to, for example, the duration of the binary signal when it stays in one of the two binary states. The regulator then uses a trigger circuit that generates a signal based on the counter signal to effectuate the modulation of the switching of the switching circuit. The reference signal may be modified by a hysteresis level adjuster to force a triggering event at the switching circuit.</p>
