TPS61087DRCR from Texas Instruments, in a VSON-10-EP(3x3). 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. |
