Power dissipation performance must be well understood prior to integrating devices on a printed-circuit board (PCB) to ensure that any given device is operated within its defined temperature limits. When a device is running, it consumes electrical energy that is transformed into heat. Most of the heat is typically generated by switching devices like MOSFETs, ICs, etc. This application report discu - D-CAP2 Frequency Response Model, based on frequency domain analysis of Fixed On-PDF, 681 Kb, 档案已发布: Jan 2, 2013
