5. Thermal consideration

The AME1086 series contain thermal limiting cir-

cuitry designed to protect itself for over-tempera-

ture conditions. Even for normal load conditions,

maximum junction temperature ratings must not

be exceed. As mention in thermal protection

section, we need to considerall sources of ther-

mal resistance between junction and ambient.

It includes junction-to-case, case-to-heat-sink in-

terface and heat sink thermal resistance itself.

Junction-to-case thermal resistance is specified

from the IC junction to the bottom of the case

directly below the die. Proper mounting is re-

quired to ensure the best possible thermal flow

from this area of the package to the heat sink.

The case of all devices in this series is electri-

cally connected to the output. Therefore, if the

case of the device must be electrically isolated,

a thermally conductive spacer is recommended.
