LM2594HVMX-5.0

Texas Instruments LM2594HVMX 5 0 NOPB · DC-DC Converters · SOIC-8

LM2594HVMX-5.0 from Texas Instruments LM2594HVMX 5 0 NOPB, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection. Datasheet notes the pin must be soldered to the PCB for best heat transfer.
2 NC unconnected No internal connection. Datasheet notes the pin must be soldered to the PCB for best heat transfer.
3 NC unconnected No internal connection. Datasheet notes the pin must be soldered to the PCB for best heat transfer.
4 Feedback input Senses the regulated output voltage to close the internal feedback loop. For fixed 5-V output versions, this pin is tied to the regulated 5-V output node. Absolute-maximum voltage range -0.3 V to 25 V.
5 ON/OFF input TTL-level shutdown input. Pulling the pin below ~1.3 V enables the regulator; pulling it above 1.3 V (up to 25 V) shuts the regulator down, dropping input supply current to approximately 80 uA. If shutdown is unused, tie to GND or leave open (regulator ON).
6 Ground power_in Circuit ground / power return for the IC.
7 +VIN power_in Positive input supply for the switching regulator. Recommended operating range 4.5 V to 60 V (HV version); absolute max 60 V. A local input bypass capacitor is required at this pin to minimize voltage transients and to supply the pulsed switching currents.
8 Output output Internal power-switch output that drives the external inductor and catch diode. The pin swings between (+VIN - VSAT) and approximately -0.5 V at ~150 kHz with duty cycle VOUT/VIN. Keep the PCB copper area on this node small to minimize EMI coupling.
