Texas Instruments · DC-DC Converters · SOT-23-3
TPS61322DBZR from Texas Instruments, in a SOT-23-3. 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 | GND | power_in | Ground reference for the IC; all voltage values on SW and VOUT are specified with respect to this terminal. |
| 2 | SW | passive | Switch node of the boost converter connected to the external inductor; absolute maximum voltage -0.3 V to 6.0 V; leakage current into SW pin 3.5 nA typical at VSW = VOUT = 1.2 × target. |
| 3 | VOUT | power_out | Regulated boost converter output supplying the load; fixed output 2.2 V (2.134 V min, 2.266 V max over -40 °C to 125 °C); quiescent current 6.5 µA typical (10 µA max) measured into this pin; absolute maximum 6.0 V. |
