TPS610986DSET from Texas Instruments, in a WSON-6(1.5x1.5). 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 | VMAIN | power_out | Boost converter output that powers the main system rail and stays enabled; the recommended boost output range is 2.2 V to 4.3 V and the boost output needs 5 µF to 22 µF effective capacitance (CO1). |
| 2 | SW | passive | Connection to the boost inductor; the absolute maximum voltage on SW is -0.3 V to 4.7 V, and the recommended inductance is 1.54 µH to 6.11 µH. |
| 3 | VIN | power_in | IC power supply input with a recommended operating range of 0.7 V to 4.5 V and an absolute maximum of -0.3 V to 4.7 V. |
| 4 | MODE | input | Mode selection: logic 1 selects Active mode and logic 0 selects Low Power mode; it must be actively tied high or low and must not be left floating, with an absolute maximum of -0.3 V to 5.0 V. |
| 5 | VSUB | power_out | LDO or load switch output for peripherals; for this load-switch variant the recommended output range is 1.8 V to 3.7 V and the absolute maximum is -0.3 V to 4.7 V. |
| 6 | GND | power_in | IC ground reference pin. |
