where RL is the inductorâs DC resistance, and the 1.1 factor is an approximation for the AC losses. If it is
expected that the internal dissipation of the LM34923 will produce excessive junction temperatures during normal
operation, good use of the PC boardâs ground plane can help to dissipate heat. Additionally the use of wide PC
board traces, where possible, can help conduct heat away from the IC. Judicious positioning of the PC board
within the end product, along with the use of any available air flow (forced or natural convection) can help reduce
the junction temperature.
