Reverse Losses...
From the above reply, am I right to say that the losses is definitely due to the reverse losses of the schottky diode? Actually, I have a query about the frequency of the regulator. What does this frequency relate to? Is it the frequency of the switching action inside the regulator? In this case, if my diode is not capable of fast switching speeds, what will happen? More power losses? For the purpose of my charger, I was actually considering placing a load capacitor before any load is connected. I wanted to maintain the potential of this capacitor for as long as possible when the supply is off so that for short durations the device I am powering can still obtain the necessary voltage. When I placed the schottky diode across, the power dissipation action is much too significant. When I substituted the diode with the pn diode, this dissipation is a lot less significant. In this case, wouldn't a pn diode be more useful, unless there is some adverse effects if I use it? Comments?
Thank you Ron :wink:
