drive current ranges from 12mA to 35mA (typical),

and is dynamically controlled according to the

power supply load change. The higher the output

power, the higher the based current. Specifically,

the base current is related to CS peak voltage, as

shown in Fig.6



Short Load Protection (SLP)

In DP2525F, the output is sampled on FB pin and

then compared with a threshold of UVP (0.65V

typically) after an internal blanking time (10ms

typical).

In DP2525F, 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 26.5V (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

28V (typical) zener clamp is integrated to prevent

the IC from damage.
