Howdy,
I'm trying to save some heat in an existing product,
automotive application.
Anyone have a fave buck synch. switcher, Joerg-cheap?
Vin: +12-28v
Vout: +5v
Iout: 4-5A
n: >=90%
<$2 for the semi's is the ballpark.
The unit has a nice Simple Switcher already, but the schottky
catch diode burns about a watt. I'd like to save that. My
attempts to sketch in a synch rectifier are partsy, pricey,
and ugly.
TIA,
James Arthur
