  Softstart Using Constant Current Constant Voltage Approach
  PDF, 337 Кб, Файл опубликован: 24 июл 2015
  In many systems backup power is provided either by batteries or simply by a large value capacitor. Inthese applications the capacitor would only provide the current when the primary power source fails.Further, these applications are usually for light load currents. During normal operation the backupcapacitors are kept charged up by a DC/DC converter. The challenge involved in an application

  AN-1286 Compensation For The LM3478 Boost Controller (Rev. C)
  PDF, 356 Кб, Версия: C, Файл опубликован: 23 апр 2013
  The LM3478 is a low side N-Channel controller for switching regulators. Like many switching controllers,the added flexibility in component selection can cause problems for users when determining thecompensation scheme. It is the goal of this application report to present a decent groundwork to allow thereader to select with confidence the correct compensation components. To achieve this we l

  AN-1484 Designing A SEPIC Converter (Rev. E)
  PDF, 220 Кб, Версия: E, Файл опубликован: 23 апр 2013
  In a single ended primary inductance converter (SEPIC) design, the output voltage can be higher or lowerthan the input voltage. The SEPIC converter shown in Figure 1 uses two inductors: L1 and L2. The twoinductors can be wound on the same core since the same voltages are applied to them throughout theswitching cycle.
