# TPS60400QDBVRQ1

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

TPS60400QDBVRQ1 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 | OUT | output | Power output with VO = -VI; bypass OUT to GND with output filter capacitor CO. |
| 2 | IN | power_in | Supply input in the range 1.8 V to 5.25 V; bypass IN to GND with a capacitor that has the same value as the flying capacitor. |
| 3 | CFLY- | passive | Negative terminal of the flying capacitor C(fly). |
| 4 | GND | power_in | Ground. |
| 5 | CFLY+ | passive | Positive terminal of the flying capacitor C(fly). |

## CAD (KiCad official)

- Symbol: `TPS60400QDBVRQ1`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- Annotated 3D hero: `tps60400qdbvrq1-hero.glb` (dashed pad outlines, silkscreen with pin 1, signal names; the [adom-hero standard](https://wiki.adom.inc/adom/component-hero)) is what the viewer shows. Downloads and EDA use the clean model, `tps60400qdbvrq1-etched.glb`.
- 3D model files: `tps60400qdbvrq1-etched.step` / `tps60400qdbvrq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps60400qdbvrq1.step` / `tps60400qdbvrq1.glb` are the bare package body.
