LM2594N-ADJ
Texas Instruments · DC-DC Converters · PDIP-8
LM2594N-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 | NC | unconnected | No internal connection on this pin. |
| 2 | NC | unconnected | No internal connection on this pin. |
| 3 | NC | unconnected | No internal connection on this pin. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop; the absolute maximum feedback pin voltage is −0.3 V to 25 V. |
| 5 | ON/OFF | input | Pulling this pin below about 1.3 V turns the regulator on and pulling it above 1.3 V (up to a maximum of 25 V) shuts it down; leaving it open or tying it to ground keeps the regulator on. |
| 6 | Ground | power_in | Circuit ground for the regulator. |
| 7 | +VIN | power_in | Positive input supply for the switching regulator, which needs a suitable input bypass capacitor; the recommended supply range for the LM2594 is 4.5 V to 40 V (absolute maximum 45 V). |
| 8 | Output | output | Internal switch output that swings between (+VIN − VSAT) and approximately −0.5 V with duty cycle VOUT/VIN, and its PCB copper area should be kept to a minimum to limit coupling to sensitive circuitry. |
