The use of the switch MOSFET
During the basic use, just connect power and ground (pins VIN and GND) and control the voltage VOUT using the built-in slide switch. To use an external switch, connect it between the GND and SW pins after the previous setting of the embedded switch in the OFF position.
Even in the OFF position, there is the possibility of monitoring the status of a switch via a digital signal (e.g. from a microcontroller) via ON pin. Low status or lack of connection leaves the switch in the OFF position, the setting of approx. 1 V at this pin, changes the switch status to "ON". The maximum value of the voltage on the ON pin can be 30 V, regardless of the voltage VIN.
The pins are the solder fields for soldering the goldpin connectors (2.54 mm pitch). Thanks to them, it is possible to connect the system to the breadboard or the main module (for example, STM32Discovery or Arduino) via wires.
