Voltage-input terminal for IC-enable/disable LED-I
A high input on this pin enables the IC to operate while a low input causes it to shut down. The behavior
of the IC is unpredictable if the input on the pin is undefined. Ensure that the pin is tied to either a high or
low level.
Over voltage detection terminal.
IC switching operation is disabled with detection over voltage.
If the voltage returns to detection level or less, operation is enabled again.
Supply voltage input terminal. (2.8 V to 5.5 V)
Switch terminal for DC-DC converter. N-ch MOSFET built-In.
