Technical Note
● Operation description
Enable control
The device can be controlled ON/OFF by EN terminal (16 pin) voltage.
An internal circuit starts when VEN reaches 1.1V.
When standing up of VIN is too steep (1msec or less), a defective start might be caused according to the state of Pascon
between GND substrate pattern and power supply-when the terminal EN is short-circuited to the terminal VIN and it is used.
