Abstract
An integrated control circuit of setting brown-in voltage and compensating output power and a method for operating the same are disclosed. The integrated control circuit is applied to a power supply. The integrated control circuit includes a control unit and a voltage regulation unit. The control unit has a control pin and a driven current outputs from or inputs into the control unit via the control pin. The voltage regulation is electrically connected to a DC input voltage terminal of the power supply and the control unit, thus receiving a DC input voltage and the driven current. By dividing the DC input voltage and the produced voltage by the driven current, a compound voltage is produced. Therefore, the fixed brown-in voltage is set and the output power is compensated when the power supply is operated under different input voltage levels.
