TPS25940LRVCR from Texas Instruments, in a WQFN-20-EP(3x4). 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 | DEVSLP | input | Active high DevSleep mode control; high voltage activates low-power DevSleep mode. |
| 2 | PGOOD | output | Active high power good open drain output; goes high when PGTH crosses threshold value. |
| 3 | PGTH | input | Positive input of PGOOD comparator. |
| 4 | OUT | output | Power output of the device. |
| 5 | OUT | output | Power output of the device. |
| 6 | OUT | output | Power output of the device. |
| 7 | OUT | output | Power output of the device. |
| 8 | OUT | output | Power output of the device. |
| 9 | IN | power_in | Power input and supply voltage of the device, 2.7V to 18V operating range. |
| 10 | IN | power_in | Power input and supply voltage of the device, 2.7V to 18V operating range. |
| 11 | IN | power_in | Power input and supply voltage of the device, 2.7V to 18V operating range. |
| 12 | IN | power_in | Power input and supply voltage of the device, 2.7V to 18V operating range. |
| 13 | IN | power_in | Power input and supply voltage of the device, 2.7V to 18V operating range. |
| 14 | EN/UVLO | input | Programmable undervoltage lockout threshold setting; when pulled to GND resets fault latch in TPS25940L. |
| 15 | OVP | input | Programmable overvoltage protection threshold setting input. |
| 16 | GND | power_in | Ground; must be connected to exposed PowerPAD using multiple vias for good thermal performance. |
| 17 | ILIM | bidirectional | Current limit control; resistor from this pin to GND sets overload and short-circuit current limit. |
| 18 | dVdT | bidirectional | Output voltage slew rate control; capacitor from this pin to GND sets ramp rate. |
| 19 | IMON | output | Current monitor output; sources scaled down ratio of current through internal FET, resistor to GND converts to proportional voltage. |
| 20 | FLT | output | Fault indicator open drain output; goes low for Undervoltage, Overvoltage, Reverse voltage, or Thermal shutdown event. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
