In the following circuit,when ON/OFF control terminal t becomes low by switching transistor Tr on, output voltage may
be turned OFF and the device becomes stand-by mode. Dissipation current at stand-by mode becomes Max.400
A.
<Soft start>
When capacitor Cs is attached, output pulse gradually expanded and output voltage will start softly.
<ON/OFF control with soft startup>
For ON/OFF control with capacitor CS, be careful not to destroy a transistor Tr by discharge current from CS, adding a
resistor restricting discharge current of CS.

In the external area of the safety operation area shown by the derating curve, the overheat protection circuit may operate to
shut-down output. However, please avoid keeping such condition for a long time.
