# TPS64203DBVR

**Texas Instruments** · DC-DC Converters · SOT-23-6

TPS64203DBVR from Texas Instruments, in a SOT-23-6. 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 | EN | input | Enable pin: a logic low enables the converter, and a logic high forces the device into shutdown mode, reducing the supply current to less than 1 µA. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback pin: connect an external voltage divider to this pin to set the output voltage, with an absolute maximum voltage at FB of −0.3 V to 3.3 V. |
| 4 | ISENSE | input | Current sense input: connect the current sense resistor between VIN and ISENSE (optional), with voltage at ISENSE limited to −0.3 V to VIN. |
| 5 | VIN | power_in | Supply voltage input, with a recommended operating range of 1.8 V to 6.5 V and an absolute maximum of 7 V. |
| 6 | SW | output | Connects to the gate of an external P-channel MOSFET, with voltage at SW limited to −0.3 V to VIN. |
