Concerning the terms BUCK and BOOST in SMPS...  The central component of the SMPS is the inductor, and, counter to its cousin, the capacitor, the inductor is basically a current-operated device.  (The capacitor, on the other hand, is a voltage operated device.)  In the SMPS design wherein the output voltage is less than the input voltage, the inductor must "BUCK" the incoming current to reduce the output voltage to the desired level.

In the case of an SMPS having an output voltage higher than the input voltage, the inductor (by means of the callapsing magnetic field and the resulting current at input current cessation) must "BOOST" the input voltage to the desired higher output voltage.

Hence the terms "BUCK" and "BOOST."

I hope this helps.
