Derating design for power supply module based on saber simulation

In this paper, the issues of derating design of integrated circuit are discussed. The disadvantage of the traditional derating design method is discussed. This paper puts forward the method using Saber to simulate the electric stress of the electronic product, which can improve the accuracy of the result and the speed of the transient stress calculation. The method that uses derating analysis based on Saber simulation is presented. By using this new method, the accuracy of the derating analysis results is greatly improved and the instantaneous stress value can be simulated. To illustrate the method, the implementation to a power supply module of an IC controller is taken as an example. Simulation results are presented to demonstrate the efficiency and accuracy of this new method.
