Texas Instruments · Global Sourcing Parts · SOIC-8
LM2597HVM-5.0 from Texas Instruments, in a SOIC-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 | Error Flag | output | Open collector output that goes low when regulated output voltage drops more than 5% from nominal, providing microprocessor reset on power-up. |
| 2 | Delay | output | Output that provides time delay between regulated output reaching 95% nominal voltage and error flag output going high at power-up. |
| 3 | Bias Supply | input | Input allowing internal circuitry to be powered from regulated output voltage or external supply instead of input voltage to increase efficiency. |
| 4 | Feedback | input | Input sensing regulated output voltage to complete feedback loop. |
| 5 | Shutdown/Soft-Start | input | Input with dual function: shutdown via logic level signal dropping input supply current to approximately 80 μA, and soft-start via capacitor providing controlled output voltage ramp-up. |
| 6 | Ground | power_in | Circuit ground. |
| 7 | +VIN | power_in | Positive input supply requiring suitable bypass capacitor to minimize voltage transients and supply switching currents. |
| 8 | Output | output | Internal switch with voltage switching between (+VIN − VSAT) and approximately −0.5 V at duty cycle VOUT/VIN, requiring minimal PCB copper area to minimize coupling to sensitive circuitry. |
