Hello
I am in the design/prototype stage of standby SMPS, specifications are below
Input range: 85VAC to 265VAC
Output-1: 12V 0.150A
Output-2: 18V 0.150A
Output 1 will be the output on the secondary side
Output 2 will be on the PRIMARY circuit side feeding ANOTHER SMPS circuit, and the GND of that output will be connected to the main GND of the main SMPS.
In another word, output 2 will be the main power source to power the MAIN SMPS.
I tried to make a design with the tool found on the site, but I never got the transformer winding details or the transformer winding method to send to the manufacturer, like what you can get in Power Expert designer.
I also don't want to face surprises with audible transformer noise!
The SMPS must NOT draw more than 0.3W in standby and in no-load conditions
Any suggestions?
