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,
Hi. Atsushi Yamauchi !
First attitude for the quiescent current: The Power supply part of device is the interface to battery. there are norms about the maximum allowed current drawn by device if it not operating and the supply is not interrupted actively…
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,
