Application Notes

  • Controlling Output Ripple & Achiev ESR Indep Constant On-Time Reg Designs (Rev. A)
    PDF, 178 Кб, Версия: A, Файл опубликован: 23 апр 2013
    Of all the voltage regulator control strategies ever devised, the hysteretic regulator is probably about thesimplest. This control methodology simply turns a switch on when the output voltage is below a referenceand turns the switch off when the output rises to a slightly higher reference. The output ripple is thereforea direct function of the difference between the upper and lower reference

  • AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)
    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
  • AN-1889 How to Measure the Loop Transfer Function of Power Supplies (Rev. A)
    PDF, 2.7 Мб, Версия: A, Файл опубликован: 23 апр 2013
    This application report shows how to measure the critical points of a bode plot with only an audiogenerator (or simple signal generator) and an oscilloscope. The method is explained in an easy to followstep-by-step manner so that a power supply designer can start performing these measurements in a shortamount of time.
  • AN-1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages (Rev. B)
    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

    PDF, 2.5 Мб, Версия: C, Файл опубликован: 24 апр 2013
    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
