The LM2672M-ADJ comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here's a brief overview of its pin functions:
1. SW (Switch Output): Connects to the output inductor and the catch diode. This is the switch node.
2. GND (Ground): Ground reference for the IC.
3. FB (Feedback): Connects to the output voltage divider used to set the output voltage.
4. ON/OFF: Used to enable or disable the device. A high level turns the regulator on, and a low level turns it off.
5. VIN (Input Voltage): Supplies the input voltage to the regulator.
6. BOOST: Provides voltage to the internal switch driver.
7. NC (No Connection): No internal connection; often used for mechanical support.
8. NC (No Connection): Another pin with no internal connection.
This configuration allows the LM2672M-ADJ to efficiently convert a higher input voltage to a lower, regulated output voltage, which can be adjusted via an external resistor network connected to the FB pin.
