  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

  Switching frequency is a very important parameter in switching power converters. As the switchingfrequency increases, the physical size of magnetic elements and other components in the circuit reducesignificantly. Switching frequency also plays a great role in control loop gain and compensation design.Switching frequency determines the maximum allowable bandwidth of the control loop. Switchi

  PDF, 82 Кб, Версия: C, Файл опубликован: 23 апр 2013
  When designing a high frequency switching regulated power supply layout is very important. Using agood layout can solve many problems associated with these types of supplies. The problems due to a badlayout are often seen at high current levels and are usually more obvious at large input to output voltagedifferentials. Some of the main problems are loss of regulation at high output current

  PDF, 9.2 Мб, Версия: B, Файл опубликован: 23 апр 2013
  This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (ОёJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP
