TPSI3050SDWZR 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 | EN | input | Active high driver enable, rated 0 to 48 V in two-wire mode and 0 to 5.5 V in three-wire mode (with respect to VSSP). |
| 2 | PXFR | input | An external resistor from PXFR to VSSP selects one of seven power transfer levels, setting the converter duty cycle in three-wire mode or the EN current limit in two-wire mode; the power transfer control input is rated 0 to 5.5 V. |
| 3 | VDDP | power_in | Primary side supply, 3.0 to 5.5 V in three-wire mode (with respect to VSSP), with 0.22 to 20 µF decoupling to VSSP. |
| 4 | VSSP | power_in | Ground supply for the primary side, the reference for the primary-side voltages (EN, PXFR, VDDP). |
| 5 | VSSS | power_in | Ground supply for the secondary side, the reference for the secondary-side voltages (VDRV, VDDH, VDDM). |
| 6 | VDDM | power_out | Generated mid supply on the secondary side, absolute maximum 6 V with respect to VSSS, with 0.003 to 40 µF decoupling across VDDM and VSSS. |
| 7 | VDDH | power_out | Generated high supply on the secondary side, absolute maximum 12 V with respect to VSSS, with VDDH to VDDM limited to 6 V and 0.003 to 40 µF decoupling across VDDH and VDDM. |
| 8 | VDRV | output | Active high driver output for the external power switch, absolute maximum 12 V with respect to VSSS, providing a nominal 10 V gate drive with 1.5/3.0 A peak source and sink current. |
