# TPS61071DDCR

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

TPS61071DDCR 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 | SW | input | Boost and rectifying switch node with internal peak current limit of 600 mA typical. |
| 2 | GND | power_in | IC ground connection for logic and power circuits. |
| 3 | EN | input | Enable input; high voltage (≥0.8×VBAT) enables operation, low voltage (≤0.2×VBAT) enters shutdown mode and disconnects load from input. |
| 4 | FB | input | Voltage feedback input for output voltage programming via external resistor divider; reference voltage 500 mV. |
| 5 | VOUT | output | Boost converter output with adjustable output voltage range 1.8 V to 5.5 V. |
| 6 | VBAT | power_in | Supply voltage input with operating range 0.9 V to 5.5 V after start-up. |
