| Zusammenfassung: | The utility model relates to a direct current is to direct -current controller's integrated circuit and direct current is to direct current converting circuit thereof. Integrated circuit connects output stage, electric current sensing network and decline resistance to produce unit and correction circuit including electric current sensing circuit, first electric current source, second electric current source, a reference voltage pin, the 2nd reference voltage pin, feedback pin, error amplifier, time. Electric current sensing circuit junction current sensing network. First electric current source and second electric current source mirror image in sensing electric current. The one end of first electric current source and decline resistance is connected to a reference voltage pin. The other end of second electric current source and decline resistance is connected to the 2nd reference voltage pin. Error amplifier connects the 2nd reference voltage pin and feedback pin. Time produces unit connection error amplifier |
