LED LIGHTING DC TO DC Buckers 12 to 10 volts?

USA Amazon source?
Low dropout voltage?
4 Amos? 2 amps?

I have never heard the term Bucker. I assumed a transformer with bucker meaning a buck/boost transformer. Learn sumpin every day.

Thanks just for info

A transformer doesn't typically have a dropout voltage either.

I guess I incorrectly assumed switching power supply, using a buck (step down) topology.

Transformers do not work on DC circuits but they make two devices that do. One is a "Voltage Regulator" like a pressure regulator in a water line it will reduce the voltage.. but it's lossy. basically it's a automatic variable resistor.

Then there are two almost alike device called a Buck/Boost or Bucker (or booster)

These "chop" the DC then either work like a switching power supply to reduce the voltage or.. In some cases INCREASE the voltage So you can put in anything from say 3 to 25 volts and get out anyting from 5 to 20 volts..

To the Original poster. Check All Electronics dot com (Make obvious changes).

Also Jamco Those would be my first suggestions.. I have one here somewhere I've not yet wired in to where it's going to go.

Davie this is not criticism.....

In distribution systems the term for an E adjustment transformer at a service drop was Bucker or Booster.

Followed by a percentage number.

Bucker 10

Booster 15

I had to help a hapless CFE CREW in Michoacan arrange an additive polarity gang of three 15 boosters at the bitter end of a 12 mile line to power a 150 horsepower cyclical water pump.

Just for help in an electronics circuit Dropout Voltage is the narrowest squeeze between two voltage. If it's too small then a booster must first be used to force an adequate differential.

Buck boost transformers are crude and rugged. The largest I have seen was a 170 Kia three phase array.

Now I understand what a bucker is. 55 year master electrician. LOL

There's any number of no-brand LED driver on Amazon, DROK constant current constant voltage for example.

DROK 5 amp, USA seller

For me, when I don't build my own, I use LED Dynamics ... consider them the Concorde Lifeline of LED drivers. I don't think they sell through Amazon, but you can get them from electronics supply houses like Future, Digikey, Mouser, Arrow.
