SLVU570A September 2011 – May 2021 TPS652510
Buck converter outputs are white and have a label for easy location. Close to any of these test points there are black ground test points to allow for DVM measurement or to use a metal exposed scope probe to reduce common mode noise measurements. All test points are described in the following table:
| Test Point | Name | Signal | COLOR | Comment |

| TP1 | GND | GND | Black | |
| TP2 | GND | GND | Black | |
| TP3 | GND | GND | Black | |
| TP4 | Vin | Vin | Black | |
| TP5 | GND | GND | Black | |
| TP6 | GND | GND | Black | |
| TP7 | GND | GND | Black | |
