Pinout
1. SW (Pin 1): Switch pin connected to the inductor and the diode.
2. GND (Pin 2): Ground pin.
3. FB (Pin 3): Feedback pin for voltage regulation. Connects to an external voltage divider.
4. SHDN (Pin 4): Shutdown pin. A high level on this pin enables the device, while a low level disables it.
5. VIN (Pin 5): Input voltage pin.
6. NC (Pin 6): No-connect pin, which should be left unconnected.
This configuration supports efficient voltage boosting for applications requiring higher voltages than the input supply, such as powering LEDs or other devices.
