WebIn the synchronous buck converter, for example, the efficiency is increased by replacing the Schottky diode with a low side MOSFET (Figure 1b). The two MOSFETs must be driven in a complimentary manner with a small dead time between their conduction intervals to avoid shoot–through. The synchronous FET operates in the third quadrant, WebMany deer hunters naturally think that the best time to shoot a mature buck is when the most does are in estrus. Wrong! The best time is about 10 days earlier, during a three-day window when the first does in a buck’s core area are coming into estrus. There are two other times during the rut when your odds are also high, but that key event ...
