Abstract: A pulse width modulation regulator IC is provided for controlling a duty cycle of at least one switch to convert one input voltage signal into an output voltage. An input pin is provided for receiving an input signal different from the input voltage signal. The input signal has a lasting time substantially the same as the time that input voltage signal situated at a high level, but the waveforms of the two signals are different. The input signal is converted into a square wave signal by a conversion unit, and a PWM signal is generated by a PWM controller according to the square wave signal to control the duty cycle of the switch. Therefore, the input pin can be saved by adjusting an internal or external circuit of the IC for the usage of the different kinds of input signals without increasing the number of input pins of the IC.

Abstract: An adaptive power converter controller coupled to a load and a power converter circuit is provided. The adaptive power converter controller has an adaptive voltage sensing unit and a converting control circuit. The adaptive voltage sensing unit is coupled to the load and output a voltage sensing signal according to a load current and a load voltage from the load. The converting control circuit is utilized for receiving the voltage sensing signal and comparing the voltage level of the voltage sensing signal with a current sensing signal, which is corresponding solely to the load current, so as to decide whether the power converter circuit is controlled according to the voltage sensing signal or the current sensing signal.
