Specialized protection for inductor and diode short circuits.

UPD prevents the IC from remaining in a “zombie” state where a minor fault (like a leaky capacitor on the OVP divider) causes partial switching, leading to overheating or audible transformer noise. UPD forces a hard retry only when the fault is fully resolved.

Internal circuits for Over-Current and Over-Temperature protection that shut down the IC to prevent permanent damage. The "Protection Pin Upd" (Update/Bypass)

Protects against hardware failures in the boost circuitry. The Role of the OVP Pin in Protection
