LM2594HVMX-12

Texas Instruments · DC-DC Converters · SOIC-8

LM2594HVMX-12 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 NC unconnected No internal connection but must be soldered to PCB for best heat transfer.
2 NC unconnected No internal connection but must be soldered to PCB for best heat transfer.
3 NC unconnected No internal connection but must be soldered to PCB for best heat transfer.
4 Feedback input Senses the regulated output voltage to complete the feedback loop; input voltage range −0.3 V to 25 V.
5 ON/OFF input Shutdown control input; pulling below 1.3 V threshold turns regulator on, pulling above 1.3 V up to 25 V maximum shuts down, or wire to ground or leave open for continuous ON operation.
6 Ground power_in Circuit ground connection.
7 +VIN power_in Positive input supply voltage 4.5 V to 60 V for LM2594HV; requires suitable bypass capacitor to minimize transients and supply switching currents.
8 Output output Internal switch output with voltage switching between (+VIN − VSAT) and approximately −0.5 V at duty cycle VOUT/VIN; keep PCB copper area minimal to reduce coupling to sensitive circuitry.
