Abstract
A switching regulator connectable to a DC power supply includes a power switch coupled between a first node and an output node and having a control gate. An output voltage feedback circuit is coupled between the output node and a feedback node. A self-oscillating power switch control circuit is coupled to the first node, the feedback node, and the power switch control gate. The power switch control circuit compares a feedback voltage to a reference voltage and provides a first control voltage to the power switch control gate when the reference voltage exceeds the feedback voltage to turn on the power switch to raise the output voltage, and a second control voltage to the power switch control gate when the feedback voltage exceeds the reference voltage to turn off the power switch to lower the output voltage.
