Pin Function Descriptions

Pin 1 - VOUT (Output Voltage): This is the main output of the converter, providing a regulated voltage based on the configuration of the internal circuitry. Users typically set this according to the desired output voltage for their application.

Pin 2 - VIN (Input Voltage): This pin is used to connect the power supply to the converter. The input voltage is converted to the regulated output voltage.

Pin 3 - GND (Ground): Connect to the ground of the circuit to ensure proper operation of the converter. All voltages are referenced to this pin.

Pin 4 - FB (Feedback): The feedback pin helps the converter adjust its output voltage by monitoring the output. A resistor divider typically connects to this pin, setting the desired output voltage.

Pin 5 - EN (Enable): By pulling this pin low, the converter is disabled and consumes minimal power. Pulling it high enables the operation of the converter. It's usually controlled by a logic signal.

Pin 6 - NC (No Connect): This pin has no electrical function in the circuit, and it can be left unconnected. It is typically used to avoid conflicts with other pins or in situations where package variations might occur.
