Hi there,

I need a power supply that runs two 5V and 160mA relay. Its efficiency must be %70-80. It is not important that it is smps or capacitive. It is my homework and i was said that this is for avert spending too much power when the tv or pc is off. Can you help me cause i can not find anything form net. Thanks.

A wall-wart is not well regulated and might not have an efficiency of 80%.

I don't know why the requirement of a that high efficiency, when your application only requires an output power of 1.2W?
