Abstract:
1. A die, the die having a die corner, the die comprising: a high-side power MOSFET having a drain and a source; a first die pad and a second die pad, each connected to the drain of the high-side power MOSFET, the first die pad having with respect to the die corner coordinates (158.3 μm±d, 2945.8 μm±d), and the second die pad having with respect to the corner coordinates (398.8 μm±d, 2959.4 μm±d), where d is not greater than 320.0 μm; a low-side power MOSFET having a drain and a source; a third die pad, a fourth die pad, a fifth die pad, and a sixth die pad, each connected to the source of the high-side power MOSFET and to the drain of the low-side power MOSFET, the third, fourth, fifth, and sixth die pads having with respect to the die corner, respectively, coordinates (599.2 μm±d, 2810.2 μm±d), (599.2 μm±d, 2465.1 μm±d), (599.2 μm±d, 2133.8 μm±d), and (599.2 μm±d, 1791.5 μm±d); a seventh die pad, an eighth die pad, a ninth die pad, and a tenth die pad, each connected to the source of the high-side power MOSFET and to the drain of the low-side power MOSFET, the seventh, eighth, ninth, and tenth die pads having with respect to the die corner, respectively, coordinates (379.5 μm±d, 1716.2 μm±d), (179.8 μm±d, 1716.2 μm±d), (417.2 μm±d, 1439.3 μm±d), and (417.2 μm±d, 1083.2 μm±d); and a fourteenth die pad, a fifteenth die pad, a sixteenth die pad, a seventeenth die pad, an eighteenth die pad, and a nineteenth die pad, each connected to the drain of the low-side power MOSFET, the fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, and nineteenth die pads having with respect to the die corner, respectively, coordinates (1466.3 μm±d, 2815.1 μm±d), (1466.3 μm±d, 2469 μm±d), and (1466.3 μm±d, 2121.9 μm±d), (1466.3 μm±d, 1774.8 μm±d), (1466.4 μm±d, 1427.7 μm±d), and (1466.4 μm±d, 1080.6 μm±d), wherein the high-side MOSFET has a first corner, a second corner, a third corner, and a fourth corner, having with respect to the die corner, respectively, coordinates (33.0 μm±d, 3022.2 μm±d), (525.3 μm±d, 2894.3 μm±d), (525.3 μm±d, 1767.1 μm±d), and (33.0 μm±d, 1767.1 μm±d), wherein the low-side MOSFET has a first corner, a second corner, a third corner, a fourth corner, a fifth corner, and a sixth corner, having with respect to the die corner, respectively, coordinates (661.6 μm±d, 3040.9 μm±d), (1407.9 μm±d, 3040.9 μm±d), (1407.9 μm±d, 976.3 μm±d), (479.5 μm±d, 976.3 μm±d), (479.5 μm±d, 1545.3 μm±d), and (661.6 μm±d, 1545.3 μm±d), wherein the coordinate of each die pad is corresponds to a geometric center of the die pad, and wherein each die pad is fully within the die and is not in contact with the edge of the die.
