TPS62125DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | GND | power_in | Ground supply pin. Connect directly to the ground plane; the exposed thermal pad must also be tied to GND. |
| 2 | VIN | power_in | Input supply pin, 3 V to 17 V (absolute max 20 V). Bypass with a low-ESR ceramic capacitor (typ. 10 uF) close to the pin. |
| 3 | EN | input | Enable-comparator input. Pulling to GND shuts the device down. The DC/DC turns on when EN rises above VTH_EN_ON (typ. 1.20 V) and off when EN falls below VTH_EN_OFF (typ. 1.15 V). Threshold can be raised via an external resistor to EN_hys. Must be terminated (do not leave floating). |
| 4 | EN_hys | output | Enable-hysteresis open-drain output. Pulled to GND while EN is below VTH_EN_ON and high-impedance once the comparator has tripped, then pulled back to GND when EN falls below VTH_EN_OFF (1.15 V typ). Used to program additional EN hysteresis; leave open or tie to GND if unused. Sink current up to 3 mA (abs max). |
| 5 | FB | input | Feedback pin for the regulator. An external resistor divider from VOUT sets the output voltage (VREF_FB = 0.808 V typ). For fixed-output-voltage variants, the divider is internal and FB is tied to VOUT. |
| 6 | VOS | input | Output-voltage sense input for the DCS-Control circuitry. Must be connected directly to the DC/DC converter output voltage. |
| 7 | SW | output | Switch node connected to the internal high-side and low-side power MOSFETs. Connect the external inductor here. Do not tie to VIN, VOUT, or GND. |
| 8 | PG | output | Open-drain power-good output. Pulled to GND when the device is disabled or VOUT is below the PG threshold; high-impedance (floating) when VOUT is in regulation. Connect via a pull-up resistor to any rail up to 10 V; sink up to 0.4 mA at spec'd VOL (abs max 10 mA). Can also serve as output-discharge path (up to ~10 mA). |
| PAD | Exposed Thermal PAD | power_in | Exposed thermal pad on the underside of the package. Must be connected to GND and to a copper area for thermal dissipation. |
