- Designing Switching Voltage Regulators with TL497APDF, 945 Kb, Archivo publicado: agosto 11, 2003
Switching voltage regulators, represented by the TL497, can achieve high-efficiency power conversion at large input/output voltage differentials. The TL497A eliminates complex circuit designs previously required and provides greater efficiency than systems using series pass regulators. The principle of operation is discussed, and practical design exercises for step-down, step-up, and inverting reg - Understanding Buck Power Stages In Switchmode Power SuppliesPDF, 173 Kb, Archivo publicado: marzo 4, 1999
A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the buck power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous - Understanding Boost Power Stages In Switchmode Power SuppliesPDF, 149 Kb, Archivo publicado: marzo 4, 1999
