The two GND pins (pin 6 and 7) separate signal ground from power ground internally. In the full PCB layout diagram, these should be connected together at a single star point near the output capacitor.
: If this part is inside a larger machine (like a chiller or CNC mill), the full diagram is often found in the Electrical Schematics section of the main machine's manual rather than the part itself. Manufacturer Portals : pbm27a210mvr diagram full
Searching for the full diagram is not a casual query. Half-diagrams or simplified block diagrams are insufficient for: The two GND pins (pin 6 and 7)
The code can be broken down:
To implement this chip in a full circuit diagram, the following elements are required: the following elements are required:
