2. Protection
The protective circuits are intended for prevention of damage caused by unexpected accidents. Do not use them
for continuous protective operation.
(1) Short Circuit Protection (SCP)
The short circuit protection block compares the FB terminal voltage with the internal reference voltage VREF. When
the FB terminal voltage has fallen below 0.4V (Typ) and remained there for 1msec (Typ), SCP stops the operation for
16msec (Typ) and subsequently initiates a restart.
