OCSET (Pin 7) = 过电流设定
Connect a resistor from this pin to the drain of the respective upper MOSFET. This resistor, an internal 40μA current source, and the upper MOSFET onresistance set the converter over-current trip point. An over-current trip cycles the soft-start function. The voltage at this pin is monitored for power-on reset (POR) purpose and pulling this pin low with an open drain device will shut down the IC.
