    Buck vs Boost Driver

    I apologize if I missed this when I searched, but what is the difference between a buck, and boost driver?

    why would I use one over the other?

    Thanks

    if you have a battery at 2 volts and you need 3.3 volts to power your led, use boost
    if you have a 14.4 volt battery and you need 3.3 volts to power your led, use buck

    Ahh ok cool. thanks for the easy explanation! Im new to LED, so is it my understanding from your response that all LEDs are driven at 3.3 volts?

    Ive looked on the site for hours, but wish there were one place here that lists info such as this.

    Again, sorry if ive missed it, just a little overwhelming.

    Thanks again

    It depends on type of your LED and current.
    Read datasheets (look for Vf) on LED manufacturer's site, for example
