Hi how can i make a PCB Mounted DC-DC step down converter which can reduce the voltage from 90V to 12V. Also, please let me know if i can buy this online
What is the output current?
Is the output to be isolated? Input Ground connects to output Ground is not isolated.
How many do you need?
Is cost important? size?
Here is something small. (not knowing what you want) Link
It was designed for 110/220 vac but most will work on DC as well. Input voltage range: AC50V-277V DC70V-390V output 12V 300mA.
