TPS54541DPRT from Texas Instruments, in a WSON-10-EP(4x4). 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. |
