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 | BOOT | output | Bootstrap capacitor pin; requires 0.1μF ceramic capacitor to PH pin for gate-drive voltage; monitoring circuit forces high-side MOSFET off when boot voltage drops below 2.1V minimum threshold. |+| 2 | VIN | power_in | Input power supply pin accepting 3.5V to 42V DC voltage for step-down buck converter operation. |+| 3 | EN | input | Enable pin with internal 0.9μA pullup current source; pull below 1.2V threshold to disable or float to enable; adjust input UVLO with external resistor divider. |+| 4 | SS/TR | input | Slow-start and tracking pin; external capacitor (0.47nF to 0.47μF) controls output voltage rise time; voltage overrides internal 0.8V reference for ratiometric sequencing applications. |+| 5 | RT/CLK | input | Resistor timing and external clock input pin; connect resistor to ground to set switching frequency (100kHz to 2500kHz) or accept external clock (300kHz to 2200kHz) for synchronization. |+| 6 | PWRGD | tri_state | Open-drain power good output; asserts low when VSENSE voltage is outside 92% to 107% window, during thermal shutdown exceeding 182°C, UVLO, or EN pin pulled below 1.25V. |+| 7 | VSENSE | input | Inverting input node of transconductance error amplifier with 97μA/V gain; connect to resistor divider from output voltage for feedback comparison to internal 0.8V reference. |+| 8 | COMP | output | Error amplifier output and peak current comparator input pin; provides control signal to PWM comparator; connect frequency compensation network to ground from this node. |+| 9 | GND | power_in | Ground connection pin; must be electrically connected to exposed thermal pad and PCB ground plane using multiple vias for proper device operation and heat dissipation. |+| 10 | PH | output | High-side MOSFET source pin serving as switching node; connected to output inductor cathode and catch diode anode; voltage swings 0V to VIN with peak inductor current capability. |+| 11 | Thermal Pad | passive | Exposed thermal pad for heat dissipation; must be soldered to PCB and connected to ground plane via multiple vias for thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-10-EP |+| Category | Power Management (PMIC) |+| Pins | 11 |++## CAD (KiCad official)++- Symbol: `TPS54140DGQR`+- Footprint: `Package_SO:MSOP-10-1EP_3x3mm_P0.5mm_EP1.68x1.88mm`+- 3D model: MSOP-10-EP (KiCad packages3D, STEP)+- 3D model files: `tps54140dgqr-etched.step` / `tps54140dgqr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps54140dgqr.step` / `tps54140dgqr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps54140) (55 pp, sha256 `b1aa27b28e4a5124`, retrieved 2026-09-22, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
