# TPS61085ATDGKTQ1

**Texas Instruments** · DC-DC Converters · VSSOP-8-0.65mm

TPS61085ATDGKTQ1 from Texas Instruments, in a VSSOP-8-0.65mm. 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 | COMP | bidirectional | Compensation pin for external compensation of the boost regulator loop. |
| 2 | FB | input | Feedback pin of the boost regulator. |
| 3 | EN | input | Shutdown control input; connect to a logic high level to enable the device. |
| 4 | PGND | power_in | Power ground pin. |
| 5 | SW | output | Switch pin of the boost converter, connected to the integrated 2 A power switch. |
| 6 | IN | power_in | Input supply pin; the recommended input voltage range is 2.3 V to 6 V. |
| 7 | FREQ | input | Frequency select pin: the switch runs at 650 kHz when FREQ is tied to GND and at 1.2 MHz when tied to IN. |
| 8 | SS | output | Soft-start control pin; connect a capacitor for soft start, or leave open for no soft start. |
