Notes

7. The PVIN, SW, and GND pins comprise the main heat conduction paths.

8. Per SEMI G38-87 and JEDEC JESD51-2 with the single-layer board (JESD51-3) horizontal.

9. Per JEDEC JESD51-6 with the board (JESD51-7) horizontal. There are no thermal vias connecting the package to the two planes in the

board.

10. Thermal resistance between the device and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on the top

surface of the board near the package.
