Understanding Thermal Dissipation and Design of a Heatsink
PDF, 59 Kb, Datei veröffentlicht: May 4, 2011
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
