Abstract:
The present disclosure provides a control apparatus of a switch-mode power supply and a switch-mode power supply. In the control apparatus of the present disclosure, a short-circuit protection module is set, and when a switching transistor of the switch-mode power supply is turned on, and the short-circuit protection module detects that a voltage across a current sensing resistor of the switch-mode power supply is less than a predetermined value within a predetermined period, that is, the current sensing resistor is short-circuited, the short-circuit protection module generates a short-circuit protection signal, and a driving controller controls the switching transistor to turn off according to the protection signal, thereby switching off the control apparatus, preventing breakdown of the switch-mode power supply, and avoiding erroneous protection.

Claim (Index 1):
A control apparatus of a switch-mode power supply, comprising:\n a driving controller, configured to collect an output voltage signal of a feedback winding of the switch-mode power supply, and to generate a driving signal for driving a switching transistor of the switch-mode power supply to turn on or off according to the output voltage signal; and a short-circuit protection module, configured to detect a voltage across a current sensing resistor of the switch-mode power supply, to generate a short-circuit protection signal when the switching transistor of the switch-mode power supply is turned on and the voltage across the current sensing resistor is less than a predetermined value within a predetermined period, and to output the short-circuit protection signal to the driving controller, wherein the driving controller is further configured to control the switching transistor to turn off according to the short-circuit protection signal.
