XL2594-5.0 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. |
| 2 | NC | unconnected | No connection. |
| 3 | NC | unconnected | No connection. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop. For the fixed 5 V variant this pin connects directly to the regulator output. Absolute max input voltage 25 V. |
| 5 | ON/OFF | input | TTL-compatible shutdown input. Pulling below ~1.3 V (up to 25 V max) turns the regulator on; pulling above ~1.3 V shuts it down (standby I_Q typ 85 µA). Can be tied to GND or left open for always-ON operation. |
| 6 | Ground | power_in | Circuit ground return for the IC. |
| 7 | +VIN | power_in | Positive input supply for the switching regulator, 4.5 V to 40 V (45 V abs max). A bypass capacitor (e.g. 68 µF) must be present at this pin to minimize voltage transients and to supply switching currents. |
| 8 | Output | output | Internal power switch output. Voltage at this pin swings between (+VIN - VSAT) and approximately -0.5 V (catch diode clamp) with a duty cycle of VOUT/VIN. Connects to the external inductor and catch diode; keep PCB copper area minimal to reduce EMI coupling. |
