how can I 220 v ac to 14or 25 dc without transformer?
I'm very new to this area. there is many chip dc-dc and 25 to 0-6 volt down converter.
but why there is no 220 v to 25 volt chip?? I don't understand...
Should I must use transformer??
I want very tiny converter. I want not using transformer or big condenser at all.
Can you help me?
Thanks
