Wondering why we have two (seemingly) identical packages for the same device? The only difference I can see is the height of the device, which begs the question - why? What is driving two different heights?
Additionally, there seems to be an inconsistency in the outline drawing on pages 25 and 26. Page 25 (DSC) shows 4 tabs from the thermal pad on each side, page 26 shows 2 tabs on each side, same as the DRC.
The TPS61202 is offered in 2 different packages. The main difference is the package height or profile.
Regarding the inconsistent package drawing for the DSC package, note 'E' on the first page explains things. The first page in the packaging drawing dimensions the package. For a given package, there can be different thermal pads. A single thermal pad version is shown on the package drawing for all packages of the same type. The governing document for the thermal pad dimensions is the second page of the package drawing. This gives exactly what the thermal pad is for this device. The third page in the packaging drawings is the land pattern and stencil for the device.
So, since the second page of the package drawing (thermal pad mechanical data) showed 2 wings/tips/fins, this is what the part actually has--not the 4 shown in the package drawing.
