  Minimizing Output Ripple During Startup
  PDF, 675 Kb, Archivo publicado: jun 22, 2017
  A buck DC/DC switching converter has a minimum on-time at which it can operate. This limits theminimum output voltage a converter can regulate to while keeping a fixed frequency. The limitation of theminimum on-time is often only considered for the steady-state output voltage; however, when the outputvoltage ramps up, in most cases the output voltage ramps up from 0 V. When the converter tri

  Understanding Thermal Dissipation and Design of a Heatsink
  PDF, 59 Kb, Archivo publicado: mayo 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
