TPS54040DGQ 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 | A bootstrap capacitor is required between BOOT and PH, and if the voltage on this capacitor falls below the minimum required by the output device, the output is forced to switch off until the capacitor is refreshed. |
| 2 | VIN | power_in | Input supply voltage, 3.5 V to 42 V (recommended operating range 3.5 V to 42 V; absolute maximum 47 V). |
| 3 | EN | input | Enable pin with an internal pull-up current source that must be pulled below 1.2 V to disable the device and can be left floating to enable it, and whose input undervoltage lockout is adjustable with two resistors. |
| 4 | SS/TR | input | Slow-start and tracking pin where an external capacitor sets the output rise time, and because this pin's voltage overrides the internal reference it can be used for tracking and sequencing. |
| 5 | RT/CLK | input | Resistor timing and external clock pin where an external resistor to ground sets the switching frequency, and if pulled above the PLL upper threshold it becomes a high-impedance synchronization clock input. |
| 6 | PWRGD | output | Open-drain power good output that asserts low when the output voltage is low due to thermal shutdown, dropout, over-voltage, or EN shutdown. |
| 7 | VSENSE | input | Inverting node of the transconductance (gm) error amplifier. |
| 8 | COMP | output | Error amplifier output and input to the output switch current comparator, to which frequency compensation components are connected. |
| 9 | GND | power_in | Ground pin. |
| 10 | PH | output | Source of the internal high-side power MOSFET, with absolute maximum output voltage of -0.6 V to 47 V (-2 V to 47 V for 10-ns transients). |
| 11 | PowerPAD | power_in | Exposed thermal PowerPAD that must be electrically connected to GND on the printed circuit board for proper operation. |
