SPV1040T from STMicroelectronics, in a TSSOP-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 | MPP-SET | input | Non-inverting input that senses the PV cell voltage and cannot be left floating; the absolute maximum range is [-5.5, VOUT] V. |
| 2 | GND | power_in | Power ground reference for the device. |
| 3 | LX | input | Booster inductor connection; the LX pin voltage range is [-5.5, VOUT] V and the maximum VOUT-to-LX drop is 5.5 V. |
| 4 | VOUT | output | Booster output voltage; the VOUT pin voltage range is [-0.3, 5.5] V, and the datasheet notes that a Schottky diode between LX and VOUT is required if VOUT above 4.8 V is needed (up to 5.2 V). |
| 5 | VCTRL | input | Inverting input of the constant voltage control loop (VREF 1.25 V typical) that cannot be left floating; the absolute maximum range is [-0.3, VOUT] V. |
| 6 | ICTRL_MINUS | input | Inverting input of the constant current control loop that must be connected to GND if unused and cannot be left floating; the absolute maximum range is [-0.3, VOUT] V. |
| 7 | ICTRL_PLUS | input | Non-inverting input of the constant current control loop that must be connected to GND if unused and cannot be left floating; the absolute maximum range is [-0.3, VOUT] V. |
| 8 | XSHUT | input | Shutdown input: low puts the device in power-off mode and high enables operation; it cannot be left floating and its absolute maximum range is [-5.5, VOUT] V. |
