I have been looking up dc-dc buck converter designs and have question regarding the diodes.
It says "5A High current Schottky diode" is it common in buck converter design to parallel diodes and I would guess this is two 2.5A diodes?
I understand that connecting them in parallel will share the load and result in a higher forward current but wont one diode try to carry a larger current due a potential for a lower forward voltage. Resulting in one diode overheating?
I know to remedy this is to add a series resistor with the diode to have a equal current drop across each resistor resulting in a almost equal current share between each diode. However this will result in a overall higher power loss due to the parallel branch and due to the large current drop in the resistor. Wouldn't you just be better paying a little more for a single diode that can meet the current requirement for your buck converter?
I would apprecitae your feedback.
