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 5):
The control apparatus according to  claim 2 , wherein the short-circuit signal generation unit comprises:\n a first MOS transistor, a second MOS transistor and a third MOS transistor, wherein a grid of the second MOS transistor is connected to a grid of the third MOS transistor, a source of the first MOS transistor is connected to a drain of the second MOS transistor, the grid of the second MOS transistor is connected to a first end of the current sensing resistor, a second end of the current sensing resistor is grounded, and a source of the second MOS transistor is connected to a drain of the first MOS transistor; a second Schmidt trigger and a fifth phase inverter connected in series, wherein an input end of the second Schmidt trigger is connected to the source of the second MOS transistor; and a second RS trigger, wherein an R end of the second RS trigger is configured to receive the logic control signal synchronous with the driving signal, an S end of the second RS trigger is connected to an output end of the fifth phase inverter, and a Q end of the second RS trigger is configured to output the short-circuit signal.
