Abstract:
A signal converter circuit includes a frequency detection circuit configured to determine whether an external control signal is a PWM signal. A PWM frequency converter circuit is configured to detect, when a PWM signal is input, a duty cycle of the PWM signal and to generate a first digital signal. An AD converter is configured to generate a second digital signal based on an input DC voltage or a voltage attributable to a variable resistor to digital data using a maximum AD convertible input voltage as a duty cycle of 100%. An output signal generation circuit is configured to generate, based on the first or second digital signals output from the PWM frequency converter circuit or the AD converter, a PWM signal with a duty cycle based on that first or second digital signals.

Claim (Index 1):
A power converter comprising:\n a signal converter circuit configured to receive an external control signal which is one of a pulse width modulation signal and a direct-current voltage, and to adjust a threshold used by a feedback circuit to detect an output voltage or electric current to be supplied to a load, wherein the signal converter circuit includes\n a frequency detection circuit configured to determine whether the external control signal is the pulse width modulation signal, \n a pulse width modulation frequency converter circuit configured to detect a duty cycle of the pulse width modulation signal and to generate a first digital signal based on the detected duty cycle, \n an analog-to-digital converter configured to generate a second digital signal based on a ratio of the direct-current voltage to a maximum analog-to-digital convertible input voltage, \n a multiplexer configured to select the first digital signal when the frequency detection circuit determines that the external control signal is the pulse width modulation signal, and to select the second digital signal when the frequency detection circuit determines that the external control signal is not the pulse width modulation signal, and \n an output signal generation circuit configured to generate as an output signal a first output pulse width modulation signal with a duty cycle based on the first digital signal when the first digital signal is selected by the multiplexer and to generate as the output signal a second output pulse width modulation signal with a duty cycle based on the second digital signal when the second digital signal is selected by the multiplexer, and to supply the output signal to the feedback circuit.
