I was trying to use ADP505x buckdesign tool I have downloaded.
ADP5050 says that switching frequency could be set to 250 kHz to 1.4 MHz.
I am trying to design a buck converter for 4 output voltages
min input voltage 12V
max input voltage 12V
1.0V 6A (1 and 2 channel paralleled)
Under advanced settings ADP505x buckdesign tool limits frequency to 450kHz
Why is that?
If I change input voltage, it changes switching frequency a bit.
Is it possible at all to achieve 1MHz switching frequency?
