LM2675N-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, connected between CB and VSW (datasheet table 4-1 specifies a 470nF capacitor; section 7.2 specifies 0.01µF, 50V ceramic for all applications). |
| 2 | NC | unconnected | No internal connection; leave unconnected. |
| 3 | NC | unconnected | No internal connection; leave unconnected. |
| 4 | FB | input | Feedback sense input; connect to the midpoint of the feedback divider for the adjustable version (VFB held at the internal reference of about 1.21V), and absolute maximum FB voltage is -0.3V to 14V, with FB never to be shorted to ground when enabled. |
| 5 | ON/OFF | input | Regulator enable input, high = on and low = off; the device is in shutdown when the pin is below about 1.4V, and the absolute maximum pin voltage is -0.1V to 6V. |
| 6 | GND | power_in | Power ground connected to system ground; keep the path to the CIN ground pin as short as possible. |
| 7 | VIN | power_in | Supply input connected to the high-side FET collector; operating input voltage is 6.5V to 40V, with an absolute maximum of 45V, and the input bypass capacitor CIN must sit close to this pin and GND. |
| 8 | VSW | output | Source of the internal high-side FET and the switch node; connect to the inductor and the external diode cathode, with the absolute maximum switch-to-ground voltage of -1V. |
