I am thinking of using the TPS61201 to supply 3.3V to my arduino project and it comes in a SON-10 package. I am having trouble understanding the land pattern and the pad numbering on the last few pages of this data sheet:
When I am looking at the page titled "Thermal Pad Mechanical Data" it shows the pin numbering as well as a pin 1 indicator on the thermal pad. I just can't tell how I am supposed to be looking at it. Is the drawing from the vantage point of a part that has the pads down on the board and I am looking at it from above, through the part to the pads....or am I looking at it as if the part is flipped upside down on its back and I am looking at the pads from the bottom? It will make a difference as to how I number the pads in my land pattern. If it is from the top looking down through the part then pad 1 on my board will either be in the top right or bottom left and if I am looking at it as if it is flipped upside down on its back then pad 1 on my board will either be bottom left or top right.
