A Tutorial on the Decibel
... dB is a dB. Using the equations P = V2/R and P = I2R to substitute for the power values, you’ll see that the ratios inside the parentheses of the decibel equation become V2/Vref2 and I2 / Iref2. Logarithms treat exponents specially: log (valueExp) = Exp × log (value). So, in the case of the voltage ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
