WebNov 29, 2014 · Coupled Inductors vs. Traditional Inductor Designs. The peak-to-peak current ripple in a traditional uncoupled buck converter can be expressed as Equation 1, where V IN is input voltage, V O is output voltage, L is the inductance value, D is a duty cycle (D = V O /V IN for a buck converter), and Fs is a switching frequency. Webthe synchronous buck converter of Figure 1. Current flowing originally from source to drain of the synchronous MOSFET, Q 2, ramps to zero, and the current in Q 1 increases to the inductor current level. Hence, the loop shaded in red and labeled “1” in Figure 1 is designated as the high-frequency switching power loop (or “hot” loop).
