TPS57140QDGQRQ1 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 | Provides bootstrap supply for high-side MOSFET gate drive; requires 0.1 μF ceramic capacitor between BOOT and PH pins. |
| 2 | VIN | power_in | Input supply voltage ranging from 3.5 V to 42 V; requires minimum 3 μF ceramic (X5R or X7R) input decoupling capacitor. |
| 3 | EN | input | Enable pin with internal pullup current source; pull below 1.2 V to disable or use resistor divider to adjust input UVLO threshold. |
| 4 | SS/TR | input | Slow-start and tracking input with internal pullup; external capacitor (0.47 nF to 0.47 μF) sets output ramp time and voltage can override 0.8 V reference. |
| 5 | RT/CLK | input | Resistor timing or external clock input for switching frequency control from 100 kHz to 2500 kHz via resistor or 300 kHz to 2200 kHz via external clock with 40 ns minimum pulse width. |
| 6 | PWRGD | tri_state | Open-drain power-good output asserts low when output voltage falls below 92% or rises above 109% of nominal 0.8 V reference with 2% hysteresis. |
| 7 | VSENSE | input | Inverting input node of transconductance error amplifier; receives scaled output voltage feedback for regulation comparison to 0.8 V reference. |
| 8 | COMP | output | Error amplifier output and PWM comparator input; route frequency compensation network (resistors and capacitors) to this pin for loop stability. |
| 9 | GND | power_in | Ground reference pin; must have electrical connection to exposed thermal pad on PCB with multiple vias for proper operation and heat dissipation. |
| 10 | PH | output | Switching node output of 200 mΩ on-resistance high-side MOSFET; connect catch diode cathode and output inductor to this pin. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
