OPERATING SEQUENCE

Power On/Power Off

Note If CTL-pin is active level after IC is powered on, This IC's Output is started Soft-Start Operation

(Output Transition Rising Time : 12ms max.).

When Power-voltage is less than UVLO operating voltage, FLG-pin is fixed on Low-Level.

If CTL1 and CTL2 pins are non-active level, this IC moves to Stand-by mode (IDD = 5

µA max.)
