tny267 price

Hi!

I design various types of control instruments.

I need a extremely low cost smps power supply capable of delivering 200mA at +/- 5V and the input should be universal input i.e. 90V to 275VAC.

Any help would be appreciated.

Thanks

Bye!

TOP is good choice for these adaptor,but not low cast.maybe a RCC converter is good choice,only need about 2-3 transistors.maybe a PWM controller,such as uc3843 and a mosfet is cheaper than TOP switch.
best wishes.

I think this lowest price solution in the market.

Re: AC adaptor design

I think low cost design. I'm favor with RCC but the lack of information needed to design such one is a trade off...

I similar to flyback but the pwm controller is in discrete mode...

Check delta power electronics, you might such one.
