LM2674N-ADJ from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CB | input | Bootstrap capacitor connection for the high-side driver; a 10nF good-quality capacitor is connected between the CB pin and the VSW pin. |
| 2 | NC | unconnected | No-connect pin with no internal connection. |
| 3 | NC | unconnected | No-connect pin with no internal connection. |
| 4 | FB | input | Feedback sense input; connect to the midpoint of the feedback divider to set VOUT on the ADJ version, or tie directly to the output capacitor on fixed-output versions. |
| 5 | ON/OFF | input | Regulator enable input: high = on, low = off; pull high or leave floating to enable the regulator, and the device is in shutdown when the pin is below 1.4V. |
| 6 | GND | power_in | Power ground pin connected to system ground; keep the distance to CIN short. |
| 7 | VIN | power_in | Power input to the high-side FET; connect to the supply and input bypass capacitor CIN, keeping the path from VIN to CIN and GND as short as possible. |
| 8 | VSW | output | Internal high-side FET source and switching node; connect to the inductor and the cathode of the external diode. |
