摘要： In a power converter, a primary coil of a transformer receives an input voltage, and a first terminal of a switch is coupled to the primary coil. An output unit includes a secondary coil of the transformer, and outputs an output voltage to which the input voltage is converted by the transformer. A switching controller receives a feedback voltage corresponding to the output voltage and a sensing voltage corresponding to a current flowing between the first terminal and a second terminal of the switch. The switching controller determines whether to perform an operation of a burst mode based on the feedback voltage. The switching controller generates a control signal by comparing the sensing voltage with a comparison voltage during a first period of the burst mode, generates the control signal by comparing the sensing voltage with a voltage corresponding to the feedback voltage during a second period of the burst mode, and transmits the control signal to a control terminal of the switch.

摘要： The present invention relates to a switch control device and a switch control method. The present invention controls a switching operation of a power switch that controls output power of a switching mode power supply (SMPS). The present invention generates an operation current corresponding to an input voltage of the SMPS and counts a compensation period in which a power supply voltage generated by the operation current increases from a predetermined counter low-reference voltage to a predetermined counter high-reference voltage. The present invention generates a compensation feedback current depending on the count result, generates a total feedback current by summing a main feedback current having a predetermined value and the compensation feedback current, and generates a power limit current of which a maximum value increases and decreases depending on the total feedback current. Turn-off of the power switch is determined by comparing the current flowing on the power switch with the power limit current.
