Application Notes

  • Softstart Using Constant Current Constant Voltage Approach
    PDF, 337 Kb, File published: Jul 24, 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 Kb, Revision: C, File published: Apr 23, 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
  • Understanding Boost Power Stages In Switchmode Power Supplies

    Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti

    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
