The Great Search: High Voltage / High Current / Low Vf Diodes
In our WLED design, we want to have two (or maybe three?) DC power inputs, where each can be up to 24V, and supply up to 5A of current into the LED strands. In our typical designs, like the Metro or Feather series, we don't really go above 1A or 2A and 20V.
Let's take a look at what is available: we want to have the lowest possible forward drop because, at 5V, we want to have no less than 4.5V going into the LEDs, but we also want to minimize the reverse current which can start to get non-trivial at these capacities.
Also, should we go with an 'ideal' diode chip or with a Schottky diode?
