LM2575M-5.0 from Texas Instruments, in a SOIC-24-300mil. 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 | PWR GND | power_in | Power ground; solder to wide PCB copper for low inductance and good thermal performance. |
| 2 | NC | unconnected | No internal connection. |
| 3 | NC | unconnected | No internal connection. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | FB | input | Feedback pin; must be wired to the regulated output voltage point on fixed-voltage versions. |
| 8 | SIG GND | power_in | Signal ground; solder to wide PCB copper. |
| 9 | NC | unconnected | No internal connection. |
| 10 | ON/OFF | input | Shutdown input; ground or drive below about 1.6V TTL for normal operation, drive high for standby, may be pulled up to VIN, and should not be left open. |
| 11 | NC | unconnected | No internal connection. |
| 12 | PWR GND | power_in | Power ground; solder to wide PCB copper for low inductance and good thermal performance. |
| 13 | NC | unconnected | No internal connection. |
| 14 | VIN | power_in | Supply input, 40V maximum operating for LM2575; bypass with at least a 47 µF electrolytic capacitor placed close to the pin. |
| 15 | VIN | power_in | Supply input, 40V maximum operating for LM2575; bypass with at least a 47 µF electrolytic capacitor placed close to the pin. |
| 16 | NC | unconnected | No internal connection. |
| 17 | OUTPUT | output | Switch output pin sourcing current to the inductor; 1A rated load current with a 2.2A typical current limit. |
| 18 | OUTPUT | output | Switch output pin sourcing current to the inductor; 1A rated load current with a 2.2A typical current limit. |
| 19 | NC | unconnected | No internal connection. |
| 20 | NC | unconnected | No internal connection. |
| 21 | NC | unconnected | No internal connection. |
| 22 | NC | unconnected | No internal connection. |
| 23 | NC | unconnected | No internal connection. |
| 24 | NC | unconnected | No internal connection. |
