Pinout
The LM2671MX-ADJ is a step-down voltage regulator with an adjustable output. It comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief overview of its pin functions:
1. Pin 1 (SW): The switch pin is connected to the inductor, and it switches between VIN and GND.
2. Pin 2 (GND): Ground pin is the reference point for the internal circuitry and power supply.
3. Pin 3 (FB): Feedback pin is used to set the output voltage. Connect it to a resistor divider network between the output and ground.
4. Pin 4 (ON/OFF): An enable pin used to turn the regulator on or off. A high voltage enables the regulator, and a low voltage disables it.
5. Pin 5 (BOOST): Boost pin improves the efficiency by driving the internal N-channel MOSFET. Connect a capacitor between this pin and the SW pin.
6. Pin 6 (VIN): Input voltage supply pin for the regulator.
7. Pin 7 (NC): No connection pin, typically not used.
8. Pin 8 (NC): Another no connection pin, typically not used.
