Derating
Figure 54: Block Diagram of Power Derating
Figure 55: Decreasing rate
Figure 56: State Machine
Power derating is enabled or disabled by an output of state machine which is decided by 4 inputs. And while the
output of state machine is 1, a decreasing rate aff ects an output power.
A decreasing rate is calculated by multiplying factor K({Power Derating P Gain}) and a diff erence between refer-
ence temperature({Power Derating Reference Temperature}) and PEBB heatsink temperature}.
An output of state machine depends on the state in which state machine is running. A transfer between states
happens when defi ned conditions are satisfi ed. Basically, if {Power Derating Enable} is 0, the state is “Disable”. And
If {Power Derating Enable} is 1, transfer is done according to PEBB heatsink temperature.
Following examples show power derating by default parameter.
