Hi,
I am designing a DC-DC converter.
Vin (Min) (V): 36
Vin (Max) (V): 75
Vout (Nom) (V): 48
Iout (Max) (A): 1
Output Power (W): 48
Isolated/Non-Isolated: Isolated
Input Type: DC
Topology: Flyback
Webench has generated a schematic for me but, some parts are missing.
It tells that diodes are custom. How can they be? and why two diodes in parallel? Do we need these diodes? if yes then please suggest an alternate part.
NPN transistor at VREF of UCC28C42 is 2N2222A this is a through-hole and costly part. Is there any alternative to this?
Regards
