The LM2678SX-ADJ is a step-down voltage regulator (buck converter) from Texas Instruments. It comes in a 7-pin TO-263 surface-mount package. Here is the pin configuration:
1. Input (VIN): Supplies the input voltage to the regulator.
2. Switch Output (SW): Connects to the inductor and is the switching output of the regulator.
3. Ground (GND): The ground pin for the regulator.
4. Feedback (FB): Receives the feedback voltage from the output for regulation and is used to set the output voltage.
5. ON/OFF: Enables or disables the regulator; connecting to ground turns the regulator on.
6. Boost (BOOST): Provides a higher supply voltage necessary for driving the gate of the internal N-channel MOSFET.
7. VCC: Provides the supply voltage for the internal control circuits and is internally connected to the output.
These pins work together to regulate the output voltage based on the input supply, making the LM2678SX-ADJ suitable for applications requiring a controlled DC output.
