• LT1534-1 Subharmonic Pulse

    I have built a 5V to 27.5V boost converter using the LT1534-1 DC/DC controller chip and observe (and hear!) the following waveform at the switch node "COL":

    I cannot replicate this waveform in LTSpice under varying load conditions, even when…

  • 推挽谐振的工作原理,LT1534的参考设计 from << Application Note 118 >>

    阅读了LT的Application Note 118--High Voltage, Low Noise, DC/DC Converters,

    对于里面基于LT1534的两个参考电路(Page4,Page5)的推挽谐振工作波形和工作阶段一直都没研究明白,特提出该问题,希望能得到解答。

    1. 因为这款芯片应该比较老了(对应的这个AN118是2008年的版本,内容介绍得很多),并不能找到对应LT1534的PSpice模型或LTSpice模型,所以首先想请问是否有相应的新的替代产品?

    需要设计的是一款输入电压约12V…

  • RE: Resonant converter design equations or app notes with transformer requirements

    The Datasheet of the LT1533 explains how to choose the magnetic for its typical application. Unfortunately, we don't have any LT1533 or LT1534 App Notes that discuss the magnetic design for the resonant converter applications.
