Hello Gents,
I'm on the Digikey / Mouser / ect design marry-go-round. I'm working on a box that is 90% digital and has a number of voltage rails. The two main rails (current wise) are 3.3 and 1.8 I'm targeting switch mode regulators. The other regs (2.5, 1.2, 1.0) are are relatively light (100 ma or less) or supply a single chip so i'm planing to use linear for them.
I am looking for a buck converter with : Iout = 1~3A, Vin > 12vdc, vout = 1.8, and has an oscillator sync input.
I'm hoping to use switching frequency 900k or above to keep the inductors small.
What do you think? Whats you favorite switching regulator?
