OFF

ON
pin stops or starts step-up operation.
Setting the
OFF
/
ON
pin to the “L” level stops operation of all the internal circuits and reduces the current
consumption significantly.
DO NOT use the
OFF
/
ON
pin in a floating state because it has the structure shown in Figure 10 and is not pulled
up or pulled down internally. DO NOT apply a voltage of between 0.3 V and 0.75 V to the
OFF
/
ON
pin because
applying such a voltage increases the current consumption. If the
OFF
/
ON
pin is not used, connect it to the VOUT
pin.
The
OFF

ON
pin does not have hysteresis.
