HBLED Driver Selection
Buck ConverterA “buck” or “step-down” takes a higher input voltage and converts it to a lower output voltage.
Boost ConverterA “boost” or “step-up”takes a lower input voltage and converts it to a higher output voltage.
Linear DriverA “linear driver” generates a fixed current that varies slightly with changes in voltage.
