LM2597HVM-5.0

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.
