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 16):
The control apparatus according to  claim 5 , wherein the delay signal generation unit comprises:\n a first resistor and a first capacitor, wherein a first end of the first resistor is configured to receive the logic control signal synchronous with the driving signal, a second end of the first resistor is connected to a first end of the first capacitor, and a second end of the first capacitor is grounded; a first Schmidt trigger, a third phase inverter and a fourth phase inverter connected in series, wherein an input end of the first Schmidt trigger is connected to the first end of the first capacitor; and a NAND gate, wherein a first input end of the NAND gate is connected to the first end of the first resistor, a second input end of the NAND gate is connected to an output end of the fourth phase inverter, and an output end of the NAND gate is configured to output the delay signal.
