either direct load current reduction or reducing the duty

cycle or duration over which the maximum load current

occurs. Die junction temperature can also be reduced by

lowering the ambient temperature or the addition of air

flow. Figure 5 shows the approximate allowable on chip

power dissipation for a given ambient temperature using

a θJA = 20°C/W.

The LT8686S contains an internal thermal shutdown fea-

ture that will stop switching if the die temperature rises

to approximately 177°C. Switching will resume when the

temperature falls approximately 5°C. This feature is not

production tested and is intended as a failsafe only.
