TPS54240DGQR from Texas Instruments, in a MSOP-10-EP. 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; if its voltage 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 (absolute maximum VIN is 47 V). |
| 3 | EN | input | Enable pin with internal pullup current source; pull below 1.2 V to disable and float to enable, and adjust the input undervoltage lockout with two resistors. |
| 4 | SS/TR | input | Slow-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 (absolute maximum 3 V). |
| 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 converts it to a high-impedance synchronization clock input (absolute maximum 3.6 V). |
| 6 | PWRGD | output | Open-drain output that asserts low if the output voltage is low due to thermal shutdown, dropout, overvoltage or EN shutdown; absolute maximum sink current is 10 mA. |
| 7 | VSENSE | input | Inverting node of the transconductance (gm) error amplifier; absolute maximum rating is -0.3 V to 3 V. |
| 8 | COMP | output | Error amplifier output and input to the output switch current comparator; frequency compensation components connect to this pin (absolute maximum -0.3 V to 3 V). |
| 9 | GND | power_in | Ground pin. |
| 10 | PH | input | Source of the internal high-side power MOSFET; absolute maximum rating is -0.6 V to 47 V, with -2 V to 47 V allowed for a 10-ns transient. |
| 11 | PowerPAD | power_in | GND pin that must be electrically connected to the exposed pad on the printed circuit board for proper operation; the voltage difference between PAD and GND is limited to ±200 mV. |
