摘要： Various methods and devices that involve control circuits for power converters are disclosed. One method comprises controlling a switch using a control signal based on a comparison signal. The switch controls a transfer of power between an input node, which receives an input, and an output node. The method comprises measuring an output of the power converter, generating an error signal based on the output, generating a periodic ramp signal with a varying period, providing the error signal to a first input terminal of a comparator, providing the ramp signal to a second input terminal of the comparator, and generating the comparison signal based on the error signal and the ramp signal using the comparator. The method comprises increasing a slope of the ramp signal in response to an increase in the input, and increasing the slope of the ramp signal in response to a decrease in the varying period.

摘要： A configuration circuit for obtaining a digital code includes a controller circuit that generates a plurality of multibit control words. A digitally controlled current source circuit receives a multibit control word generated by the controller circuit. The digitally controlled current source circuit generates an output current that corresponds to the multibit control word in accordance with a predetermined output curve. A test voltage node receives the output current, and a test voltage develops in response to the output current. A reference voltage node develops a reference voltage, the level of which is independent of the multibit control word. A voltage comparison circuit (i) receives the test voltage and the reference voltage, (ii) compares the two voltages to produce a comparison result and (iii) sends the comparison result to the controller circuit. The digital code is obtained by the configuration circuit using the comparison result and the multibit control word.
