# TPS61222DCKT

**Texas Instruments** · DC-DC Converters · SC-70-6(SOT-363)

TPS61222DCKT from Texas Instruments, in a SC-70-6(SOT-363). 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 | VIN | power_in | Boost converter input voltage, operating range 0.7 V to 5.5 V, with absolute maximum rating of -0.3 V to 7.5 V. |
| 2 | FB | input | Voltage feedback input for the adjustable version; on fixed-output versions such as the TPS61222 (5.0 V) it must be connected to VOUT, and absolute maximum rating is -0.3 V to 7.5 V. |
| 3 | GND | power_in | Control/logic and power ground for the device. |
| 4 | VOUT | power_out | Boost converter output voltage; for the TPS61222 it is 5.0 V typical (4.82 V to 5.13 V), with absolute maximum rating of -0.3 V to 7.5 V. |
| 5 | L | passive | Connection for the boost inductor (switch node), with absolute maximum rating of -0.3 V to 7.5 V. |
| 6 | EN | input | Enable input (1: enabled, 0: disabled) that must be actively tied high or low and must not be left floating; absolute maximum rating is -0.3 V to 7.5 V. |
