TPS54040DGQR 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 for high-side MOSFET gate drive, requiring 0.1 μF ceramic capacitor between BOOT and PH to provide gate voltage. |
| 2 | VIN | power_in | Input power supply voltage with operating range 3.5 V to 42 V and absolute maximum rating of 47 V. |
| 3 | EN | input | Enable control input with enable threshold 0.9 V to 1.55 V and internal pull-up current source for adjustable input UVLO. |
| 4 | SS/TR | input | Slow-start and tracking input for setting output voltage rise time using external capacitor with 2 μA internal charge current. |
| 5 | RT/CLK | input | Resistor timing and external clock input for adjusting switching frequency from 100 kHz to 2500 kHz via resistor or external synchronization signal. |
| 6 | PWRGD | tri_state | Open-drain power-good output asserted low when output voltage is outside 94% to 107% of nominal reference or during thermal shutdown/UVLO. |
| 7 | VSENSE | input | Inverting input to transconductance error amplifier for output voltage feedback with maximum rating −0.3 V to 3 V. |
| 8 | COMP | output | Error amplifier output with DC gain 10,000 V/V and transconductance 97 μA/V for external frequency compensation network connection. |
| 9 | GND | power_in | Ground reference and return path, must be electrically connected to exposed thermal pad for proper operation. |
| 10 | PH | output | High-side MOSFET source and switching node connecting to output inductor and catch diode with voltage rating −0.6 V to 47 V. |
| 11 | PowerPAD | power_in | Exposed thermal pad electrically connected to GND, required for thermal management and junction temperature control of IC. |
