The TPS61170 comes in a thermally enhanced QFN package. This package includes a thermal pad that
improves the thermal capabilities of the package. The R
θ
JA
of the QFN package greatly depends on the PCB
layout and thermal pad connection. The thermal pad must be soldered to the analog ground on the PCB. Using
thermal vias underneath the thermal pad as illustrated in the layout example. Also see the
