  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
