dear freinds
i am trying to design a regulated power supply of 18 v dc witch can work in
the range of 220v to 90 v ac.
any body have an idea ,please guide me soon.
thanks
after many years of development, we are fortunate to have a broad array of COTS powe regulation products. Also, thermal analysis must be taken into account to make sure the safety issues, which is the overriding concern about power regulation design.
hussain, do you have any targets for regulation?
I have found **broken link removed**; the max current rating is 30mA, but you can boost the current with out-bound transistors.
