XL2594-12

XINLUDA · AC-DC Controllers and Regulators · SOP-8

XL2594-12 from XINLUDA, in a SOP-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 connection. Leave floating or tie to ground for best PCB layout.
2 NC unconnected No connection. Leave floating or tie to ground for best PCB layout.
3 NC unconnected No connection. Leave floating or tie to ground for best PCB layout.
4 Feedback input Senses the regulated output voltage to complete the feedback loop. For the fixed 12-V version, connect directly to the regulated 12-V output node. Absolute maximum voltage: -0.3 V to 25 V.
5 ON/OFF input TTL-compatible shutdown input. Pulling this pin below the ~1.3-V threshold turns the regulator ON; pulling it above 1.3 V (up to 25 V maximum) shuts the regulator OFF and drops supply current to approximately 85 µA standby. If unused, tie to GND or leave open (regulator remains ON).
6 GND power_in Circuit ground reference for the IC.
7 +VIN power_in Positive input supply for the IC switching regulator. Operating range 4.5 V to 40 V (absolute max 45 V). A low-ESR input bypass capacitor must be placed close to this pin to minimize voltage transients and supply the switching currents.
8 Output output Internal power switch output. The voltage at this pin switches between (+VIN - VSAT) and approximately -0.5 V with duty cycle of VOUT/VIN. Connects to the external inductor and catch diode of the buck converter. Delivers up to 0.5 A. Steady-state voltage to ground min: -1 V.
