  • Calculating Efficiency
    PDF, 175 Kb, Archivo publicado: feb 19, 2010
    This application report provides a step-by-step procedure for calculating buck converter efficiency and power dissipation at operating points not provided by the data sheet.
  • Designing Type III Compensation for Current Mode Step-Down Converters (Rev. A)
    PDF, 298 Kb, Revisión: A, Archivo publicado: sept 15, 2010
    One of the well-known benefits of current-mode control is that the system stability can be easily achieved by Type II compensation design. It is possible to improve the transient response of a current mode DC/DC converter by adopting Type III compensation to boost the crossover frequency and phase margin. Type III compensation is simple to design and needs only one extra component.
  • 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
