# TLV61046ADBVR

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

TLV61046ADBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | passive | Switch pin of the boost converter, connected to the drain of the internal low-side power MOSFET. Connect the external inductor between VIN and SW. Rated to 32 V absolute maximum. |
| 2 | GND | power_in | Device ground reference. Connect to the ground plane with a low-impedance path. |
| 3 | FB | input | Feedback input for adjustable output voltage. Connect to the center tap of an external resistor divider from VOUT to set the output voltage (VREF = 0.795 V typical). Tying FB to VIN selects the internal default 12-V fixed output. |
| 4 | EN | input | Enable logic input. Logic high (>1.2 V) enables the device; logic low (<0.4 V) forces shutdown mode with the isolation switch open. Do not leave floating. |
| 5 | VOUT | power_out | Boost converter output. Provides 3.3 V to 28 V (default fixed 12 V) through the internal isolation switch and integrated power diode. Rated to 32 V absolute maximum; connect the output capacitor here. |
| 6 | VIN | power_in | IC power supply input, 1.8 V to 5.5 V (operates down to 1.6 V after start-up). Bypass with the input capacitor close to the pin. Absolute maximum 6 V. |
