Flow through short circuit on the output side by one measuring resistance, and the need to protect the current into a voltage value, the voltage value into the op-amp, it compared with the reference voltage, can get a signal, is used to control whether protection, over current can be protected,
Can be said that short circuit is over-current limit state?
Just at this time due to short circuit, the output voltage, cooperate with the mosfet current limiting resistor to control the output power, short circuit protection can be realized,
