Abstract:
A control circuit of a power supply is provided. The power supply includes a current-sense circuit, a voltage-sense circuit, an output voltage regulation circuit, and a current regulation circuit. The current-sense circuit generates a current-sense signal in response to an output current of the power supply. The voltage-sense circuit generates a voltage-sense signal in response to an output voltage of the power supply. The output voltage regulation circuit is coupled to regulate the output voltage of the power supply according to a voltage reference signal and the voltage-sense signal. The output current regulation circuit is coupled to regulate the output current of the power supply according to a current reference signal and the current-sense signal. The output voltage of said power supply is programmable.
