• LM20145-Q1: recommended crossover frequency

  

  Takao Yamamoto

  Dear all, Could you teach me recommended crossover frequency if there is recommended value. I used WEBENCH, and set crossover frequency to about 150kHz at SW=503kHz. Is this OK? Best regards,

  Dear all, At WEBENCH, why you select 25V capacitor? Could you teach me the reason? *see attached file LM20145WEBENCH.pdf At data sheet, you select 6.3V capacitor. What is this difference? Which one should we choose? Best regards,
