# TPS6735ID

**Texas Instruments** · DC-DC Converters · SOIC-8

TPS6735ID from Texas Instruments, in a SOIC-8. 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 logic input; EN > 2 V turns on the converter, EN ≤ 0.4 V turns it off. |
| 2 | REF | output | 1.22-V reference voltage output; can source 125 µA for external loads. |
| 3 | SS | output | Soft-start control node; a capacitor between SS and GND brings the output voltage up slowly. |
| 4 | COMP | output | Compensation node; a capacitor to ground stabilizes the feedback loop. |
| 5 | FB | input | Feedback input connected to the dc/dc converter output. |
| 6 | GND | power_in | Ground reference. |
| 7 | OUT | output | Power MOSFET drain connection providing the negative output. |
| 8 | VCC | power_in | Supply-voltage input; 4 V to 6.2 V operating range. |

## CAD (KiCad official)

- Symbol: `TPS6735ID`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tps6735id-etched.step` / `tps6735id-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps6735id.step` / `tps6735id.glb` are the bare package body.
