# TPS62203DBVT

**Texas Instruments** · DC-DC Converters · SOT-23-5

TPS62203DBVT from Texas Instruments, in a SOT-23-5. 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 | VI | power_in | Supply voltage pin; the datasheet recommends a supply of 2.5 V to 6.0 V, with an absolute maximum of 7.0 V. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | EN | input | Enable pin: pulling it to ground forces shutdown mode, pulling it to VI enables the device, and it must not be left floating. |
| 4 | FB | input | Feedback pin: connect directly to the output for the fixed-output version, or to an external resistor divider for the adjustable version, where the internal divider is disabled. |
| 5 | SW | bidirectional | Switch pin connected to the internal MOSFET switches; the inductor connects to this pin. |
