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 9):
The control apparatus according to  claim 8 , wherein the driving controller comprises:\n a sampling module, wherein an input end of the sampling module is configured to receive the output voltage signal of the feedback winding, and the sampling module is configured to sample the output voltage signal of the feedback winding; an error amplifier, wherein a negative input end of the error amplifier is connected to an output end of the sampling module; a TDS detecting module, wherein an input end of the TDS detecting module is connected to the input end of the sampling module, and an output end of the TDS detecting module is connected to an output end of the error amplifier; and a constant-voltage and constant-current control module, a logic control module, and a driving module connected in series, wherein an input end of the constant-voltage and constant-current control module is connected to the output end of the error amplifier, the driving module is configured to generate the driving signal for driving the switching transistor to turn on or off according to a logic signal output by the logic control module, and the overcurrent protection module and the short-circuit protection module are connected to the logic control module.
