TPS57040QDGQRQ1 from Texas Instruments, in a HVSSOP-10-EP-0.5mm. 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 | Bootstrap capacitor supply pin; output device is forced off if voltage drops below the minimum required by the output device. |
| 2 | VIN | power_in | Input supply voltage pin accepting 3.5 V to 42 V. |
| 3 | EN | input | Enable pin with internal pull-up current source; pull below 1.2 V to disable or float to enable device and adjust input undervoltage lockout with two resistors. |
| 4 | SS/TR | input | Slow-start and tracking input pin; external capacitor sets output rise time and voltage on this pin overrides internal reference for tracking and sequencing. |
| 5 | RT/CLK | input | Resistor timing and external clock input pin; holds fixed voltage with external resistor to ground for switching frequency setting or becomes high impedance clock input if pulled above PLL upper threshold. |
| 6 | PWRGD | output | Open drain power-good output; asserts low when output voltage is low due to thermal shutdown, dropout, overvoltage, or EN shutdown. |
| 7 | VSENSE | input | Inverting input node of the transconductance error amplifier for output voltage feedback. |
| 8 | COMP | output | Error amplifier output node and input to the output switch current comparator; connect frequency compensation components to this pin. |
| 9 | GND | power_in | Ground return pin. |
| 10 | PH | input | Source of the internal high-side power MOSFET switching node connecting to external inductor. |
| 11 | Thermal Pad | power_in | Exposed thermal pad on printed circuit board electrically connected to GND; must be connected for proper thermal and electrical operation. |
