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 4):
The control apparatus according to  claim 2 , wherein the short-circuit signal generation unit comprises:\n a first comparator, wherein a negative input end of the first comparator is connected to a first end of the current sensing resistor, a second end of the current sensing resistor is grounded, and a positive input end of the first comparator is connected to a first reference voltage; a first phase inverter and a second phase inverter connected in series, wherein an output end of the first comparator is connected to an input end of the first phase inverter; and a first RS trigger, wherein an R end of the first RS trigger is configured to receive the logic control signal synchronous with the driving signal, an S end of the first RS trigger is connected to an output end of the second phase inverter, and a Q end of the first RS trigger is configured to output the short-circuit signal.
