Pinout
Here is a brief overview of the pin functions:
1. SW (Pin 1): This is the switch pin. It connects to the inductor and is the switching output.
2. GND (Pin 2): Ground pin, serves as the return path for the IC.
3. FB (Pin 3): Feedback pin, used to set the output voltage through an external resistor divider network.
4. EN (Pin 4): Enable pin, used to enable or disable the device. A high level turns the device on, and a low level turns it off.
5. VIN (Pin 5): Input voltage supply pin, where the input voltage is supplied to the device.
6. NC (Pin 6): This pin is typically not connected internally and can be left floating or connected to ground.
These pins work together to regulate and boost the input voltage to the desired output level.
