摘要： A voltage converting circuit including a power stage, a filter, a comparator, a first and a second feedback units. The power stage receives an input voltage and outputs the input voltage according to a duty cycle. The filter receives the input voltage to convert the input voltage into a current, and filters the current to obtain an output voltage. The first feedback unit amplifies a difference between a reference voltage and the output voltage to obtain an error voltage. The second feedback unit calculates the quadratic differential and integration of the output voltage to obtain a sensing voltage. The comparator compares the error voltage and the sensing voltage, and outputs a comparing result to adjust a duty ratio. Herein, a ripple of the output voltage is linearly proportional to that of the current, and DC divided voltage level of the output voltage is substantially equal to the reference voltage.

摘要： The present invention discloses a buck switching regulator including a power stage, a driver circuit and a bootstrap capacitor. The power stage includes an upper-gate switch, a lower-gate switch and an inductor. The upper-gate switch is electrically connected between an input terminal and a switching node. The lower-gate switch is electrically connected between the switching node and ground. The bootstrap capacitor is electrically connected between a boost node and the switching node, wherein the boost node is electrically connected to a voltage supply. When a voltage across the bootstrap capacitor is smaller than a reference voltage, the lower-gate switch is turned on to charge the bootstrap capacitor from the voltage supply. When the charging operation to the bootstrap capacitor has been conducted over a predetermined time period or when the current of the inductor has reached a predetermined value, the charging operation to the bootstrap capacitor is ceased.
