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!

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. rgds, bryan
