Hey guys,
Just want to ask what is the favorite smps for powering MCUs. I'm looking for a generic DC-DC converter to power future designs which will mostly be 3V3 rail based in my case. The source is automotive therefore between 12v(min)~14.5v(max) DC > Step-down to 5V > to 3V3 LDO > to MCU.
Reason I ask is I am feeling much like my wife in a cosmetic store facing a marketing panel of eternal colors, packaging, scents and other gimmicks. Whether that is pros & cons of low/mid/high switching freq, requires more or less passives, better/worst efficiencies, price, noise, ripple specs, rms competition, the list goes on and on forever I could test/breadboard smps for the next 170 months to find one that finally outputs DC lol. At the end of the day, I just need 3V3 really
So...
What is "The Chip" guys?
