The XZ1003 includes comprehensive protection features to ensure safe and reliable operation: (1) Over-Current Protection (OCP): Cycle-by-cycle current limiting prevents damage during output short circuits or overload conditions. (2) Over-Voltage Protection (OVP): Monitors output voltage and shuts down the converter if voltage exceeds safe limits. (3) Under-Voltage Lockout (UVLO): Prevents operation when input voltage is insufficient, ensuring proper startup behavior. (4) Thermal Shutdown (TSD): Automatically disables the device if junction temperature exceeds safe operating limits, with automatic restart when cooled. (5) Soft-Start Function: Gradually ramps output voltage to prevent inrush current and voltage overshoot during startup. (6) Power-Good Indicator: Provides status signal when output voltage is within regulation.

Verify protection features meet your system safety requirements. Contact FAE for protection feature customization if needed.
