s ON/OFF Control Terminal
1. In the following circuit,when ON/OFF control terminal 5 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.400µA.
2. Soft start
When capacitor Cs is attached, output pulse gradually expanded and output voltage will start softly.
3. 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.
