#104541 - switching frequency?
Responding to: ???'s previous message
Once I used a DC/DC converter in an audio projet and found, that only a pi-filter yielded satisfying results. That's why I suggested it here.


Kai,

At what frequency was your switcher switching? I used one of the Linear Tech switchers in a USB audio thing. I switched at 1.2 MHz (small inductors and caps!) to generate 5.25V from USB Vcc, and further downregulated to 5.00 V using Micrel low-noise linear regs. Worked well.
