TPS61085PWR from Texas Instruments, in a TSSOP-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 | COMP | bidirectional | Compensation pin for external RC feedback network connected to error amplifier for loop stability optimization. |
| 2 | FB | input | Feedback input from output voltage divider; nominal regulation voltage 1.238 V. |
| 3 | EN | input | Enable/shutdown control input; device enabled when EN ≥ 2 V (logic high), disabled when EN ≤ 0.5 V (logic low). |
| 4 | PGND | power_in | Power ground reference. |
| 5 | SW | output | Switch node output driven by internal 2.0-A MOSFET with 0.13-Ω on-resistance; connection to external boost inductor. |
| 6 | IN | power_in | Input supply pin; recommended operating range 2.3 V to 6 V for boost conversion up to 18.5 V. |
| 7 | FREQ | input | Frequency select input; connect to GND for 650 kHz or to IN for 1.2 MHz switching frequency. |
| 8 | SS | output | Soft-start control output; external capacitor connection to manage startup transient and limit inrush current. |
