ON/OFF pin
For current detection.
Sink current is about 55μA. The current limiter comparator
works when an external resistor is connected between this pin
and VIN, and if the voltage of this resistor is less than the
voltage of RSNS then Pch MOS is turned off. This operation is
reset each PWM pulse.
Supply voltage pin．
It is observed by the UVLO function. When its voltage becomes
3.4V or more, ICs startup in soft start.
Current detection resistor connection pin.
Resistor is connected between VIN and this pin, and the current
flows to MOSFET are measured.
