WebMOSFET Q1 is turned on. Increased power dissipation due to the diode reverse recovery current can occur if this happens. Another characteristic of the synchronous buck power stage is that it always operates in continuous conduction mode (CCM) because current can reverse in Q2. Thus the voltage conversion relationship and the duty-cycle-to-output WebOct 28, 2015 · Reverse recovery in a diode is the flow of reverse current (the wrong way!) through the diode as reverse voltage is applied across the terminals (see Figure 2). There is stored charge in the diode that must …
