TPS54140ADGQR from Texas Instruments, in a MSOP-10-EP. 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 node requiring 0.1 μF capacitor to PH pin for high-side gate driver supply from internal regulator. |
| 2 | VIN | power_in | Input supply voltage with operating range of 3.5 V to 42 V. |
| 3 | EN | input | Enable pin with internal pull-up; pull below 1.2 V to disable or float to enable, with adjustable UVLO voltage via external resistors. |
| 4 | SS/TR | bidirectional | Slow-start and tracking pin where external capacitor sets output rise time and voltage overrides internal reference for power sequencing. |
| 5 | RT/CLK | input | Timing resistor or external clock input; internal amplifier maintains fixed voltage for frequency setting or acts as PLL synchronization input. |
| 6 | PWRGD | output | Open-drain power-good output asserts low when output voltage is low due to thermal shutdown, dropout, over-voltage, or EN shutdown. |
| 7 | VSENSE | input | Inverting input of transconductance error amplifier connected to output feedback voltage divider. |
| 8 | COMP | output | Error amplifier output for connection of frequency compensation components. |
| 9 | GND | power_in | Ground reference and connection point to exposed thermal pad on PCB. |
| 10 | PH | output | Source of internal high-side power MOSFET serving as switching node connected to output inductor and catch diode. |
| 11 | Thermal Pad | passive | Exposed ground pad that must be soldered to PCB for optimal thermal and mechanical performance. |
