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.
