Short Load Protection (SLP)
In DP2525, the output is sampled on FB pin and
then compared with a threshold of UVP (0.6V
typically) after an internal blanking time (10ms
typical).
In DP2525, when sensed FB voltage is below 0.6V,
the IC will enter into Short Load Protection (SLP)
mode, in which the IC will enter into auto recovery
protection mode.
VDD Over Voltage Protection (OVP) and
Zener Clamp
When VDD voltage is higher than 27.5V (typical),
the IC will stop switching. This will cause VDD fall
down to be lower than VDD_OFF (typical 6.5V) and
then the system will restart up again. An internal
30V (typical) zener clamp is integrated to prevent
the IC from damage.
