I am looked for a switching stepdown dc-dc voltage regulator that can be ganged together with multiple slave units and one master to allow increased output current capacity. I know I’ve seen one in the past but haven’t been able to find it. Is there a particular term I can search.
Looking for 12V output 15-24V input, 1+A output current each.
Greetings,
Just how much current are you looking for? A person can get board-mountable DC-DC converter solutions that reach into kW territory these days if one care$ enough.
There are also “regulator” (integrated power switch, bring your own magnetics) ICs that are good for a rather respectable number of amps, and “controller” (BYO switch and magnetics) for which the question of current capacity isn’t really defined, since it’s up to the user to define the limiting elements in that case.
A person could probably find examples among each of devices that facilitate parallel operation as an on-label feature, but it’s honestly not something that’s very well exposed parametrically. Which is perhaps understandable, since folks are usually interested in reducing parts count where possible. Presence of a “sync” feature can be a cue, albeit a reliable one.
Ok ya got me there, I should have a better answer as to why I want to gang these things together.
Honestly there are way too many choices and I think I got seduced by the low cost of items like the TI Simple Switcher and after getting good results prototyping a couple I figured I’d stick to what works and just multiply.
I should probably just pony up for a COTS PS as this is in support of a hobby project that entails many far more interesting problems than reinventing this wheel. Thanks for the helpful links that point up how far out of my depth I am.
