Many of the newer bike lights use LEDs. Although I understand basic electronics it has been some years since I learned electronic theory. Although I understand the basics of buck and boost drivers I have some questions about how they operate.
Question one: Is it possible that a driver can supply more current to a load than the current that is delivered to the driver from the battery ( or voltage source )? This has been something that I have wondered about for some time. I always thought that the max. current supplied by the voltage source was the same as the max. current supplied and delivered through the load powered by the driver. I've heard that this is not so and that a driver can deliver more current ( depending on the design and components used to build the driver ). Is this possible?
Put another way; Is there such a thing as a boost driver that not only regulates current but boosts current as well?
