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 | BOOT | output | A bootstrap capacitor is required between BOOT and SW; if its voltage falls below the minimum needed to operate the high-side MOSFET, the gate drive is switched off until the capacitor is refreshed. |+| 2 | VIN | power_in | Input supply voltage with a 4.5 V to 42 V operating range. |+| 3 | EN | input | Enable pin with an internal pullup current source; pull below 1.2 V to disable and float to enable, and the input undervoltage lockout can be adjusted with two resistors. |+| 4 | SS/TR | input | Soft-start and tracking pin; an external capacitor sets the output rise time, and because this pin overrides the internal reference it can be used for tracking and sequencing. |+| 5 | RT/CLK | input | Resistor timing and external clock pin: an external resistor to ground sets the switching frequency, and pulling the pin above the PLL upper threshold makes it a high-impedance synchronization clock input. |+| 6 | FB | input | Inverting input of the transconductance (gm) error amplifier. |+| 7 | COMP | output | Error amplifier output and input to the output switch current (PWM) comparator; frequency compensation components connect to this pin. |+| 8 | GND | power_in | Ground pin, which must be electrically connected to the exposed thermal pad on the printed circuit board for proper operation. |+| 9 | SW | output | Source of the internal high-side power MOSFET and the switching node of the converter. |+| 10 | PWRGD | output | Power Good open-drain output that asserts low if the output voltage is out of regulation due to thermal shutdown, dropout, over-voltage, or EN shutdown. |+| 11 | Thermal Pad | power_in | Exposed thermal pad that must be electrically connected to the GND pin and the printed circuit board for proper operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-10-EP(4x4) |+| Category | Power Supply Chip |+| Pins | 11 |++## CAD (KiCad official)++- Symbol: `TPS54541DPRT`+- Footprint: `Package_SON:WSON-10-1EP_4x4mm_P0.8mm_EP2.6x3mm`+- 3D model: WSON-10-EP(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps54541dprt-etched.step` / `tps54541dprt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps54541dprt.step` / `tps54541dprt.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/tps54541) (54 pp, sha256 `4b1d01bc1ac54658`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
