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 | COMP | bidirectional | Compensation pin. External RC network to GND sets the loop compensation for the error amplifier. |+| 2 | FB | input | Feedback pin. Connect to the midpoint of the external resistor divider from the boost output to set the regulated output voltage (internal reference ~1.238 V). |+| 3 | EN | input | Shutdown control input. Connect this pin to a logic high level to enable the device; logic low places the device in shutdown. |+| 4 | AGND | power_in | Analog ground. Also connects to the exposed thermal pad on the bottom of the package. |+| 5 | PGND | power_in | Power ground. Return path for the internal 3.2-A power switch; connect directly to the input capacitor ground with a low-impedance trace. |+| 6 | SW | power_in | Switch pin. Drain of the internal NMOS power switch; connect to the inductor and the anode of the boost rectifier diode. Pins 6 and 7 must be tied together. |+| 7 | SW | power_in | Switch pin. Second SW pin, internally tied with pin 6 for reduced conduction losses; connect together to the inductor / diode node. |+| 8 | IN | power_in | Input supply pin. Connect the 2.5-V to 6-V input rail with a local bypass capacitor (typ. 1 µF) close to the pin. |+| 9 | FREQ | input | Frequency select pin. The power switch operates at 650 kHz when FREQ is tied to GND and at 1.2 MHz when FREQ is tied to IN. |+| 10 | SS | output | Soft-start control pin. Connect a capacitor from this pin to GND to program the soft-start ramp (e.g. 100 nF). Leave open to disable soft-start. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSON-10-EP(3x3) |+| Category | PMIC |+| Pins | 10 |++## Ordering variants++Same part, different packaging or reel option.++- `TPS61087DRCR`+- `TPS61087DRCRDRCT`+- `TPS61087DRCRDSCR`+- `TPS61087DRCRDSCT`++## CAD (KiCad official)++- Symbol: `TPS61087DRCR`+- Footprint: `Package_SON:VSON-10-1EP_3x3mm_P0.5mm_EP1.2x2mm`+- 3D model: VSON-10-EP(3x3) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps61087.pdf) (37 pp, sha256 `04420ae78177db4b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
