VOUT Short-Circuit Protection （SCP） ? The feature prevents potentially uncontrolled inductor current if VOUT is overloaded or shorted to ground ? The output is shut down when the fault latch is occurred ? Once the fault condition is removed， cycle VIN to clear the fault latch ? Over Current Protection （OCP） ? To limit the inductor current， the device has a cycle-bycycle current limit ? The MOS switch is turned off when OCP is occurred.

　　? VOUT Overvoltage Protection （OVP） ? To protect Boost switch in case the feedback is floating or shorted to ground ? The MOS switch is turned off when OVP is occurred and the converter continues to operate when VOUT falls below the overvoltage threshold ? Thermal Shutdown （OTP） ? To prevent damage caused by excessive heat and power dissipation ? The device is shut down when OTP is occurred ? Once the device cools down， cycle VIN to clear the fault latch
