# TPS610981DSET

**Texas Instruments** · DC-DC Converters · WSON-6(1.5x1.5)

TPS610981DSET 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 supplies the always-on main system rail, with a recommended output voltage range of 2.2 V to 4.3 V and an effective output capacitance of 5 µF to 22 µF. |
| 2 | SW | power_out | Connection to the boost converter inductor (effective inductance 1.54 µH to 6.11 µH, 4.7 µH nominal), with the SW pin rated to the −0.3 V to 4.7 V absolute maximum range shared by VIN, SW, VMAIN and VSUB. |
| 3 | VIN | power_in | IC power supply input with a recommended input voltage range of 0.7 V to 4.5 V and an absolute maximum range of −0.3 V to 4.7 V. |
| 4 | MODE | input | Mode selection pin where 1 selects active mode and 0 selects low power mode; it must be actively tied high or low and must not be left floating, with an absolute maximum range of −0.3 V to 5.0 V. |
| 5 | VSUB | power_out | LDO or load switch output that powers the peripherals, with a recommended output voltage range of 1.8 V to 3.7 V; the required output capacitance depends on the LDO or load switch version. |
| 6 | GND | power_in | IC ground reference pin. |
