1W Power Supply - Please Review
Posted by: tylerjbrooks

I need a 1W power supply much like the one shown in Design Example DI-138. Specifically, I need the following:
VCC = 20mA @ 15V
VEE = 80mA @ 3.3V
VSS = 20mA @ -15V
My power supply design is attached.
I am just wondering two things:
1) Is this the right approach for a low cost, dual rail 1W power supply? Is there another technique I should look at?
2) Can you suggest any improvements or cost savings to this design?

Thankyou for the feedback Surak.
Two last question:
1) No spice model for the LNK305 ? Why not? It would allow me to experiment without having to build up the circuit.
2) Could I reference this power supply to 'hot' instead of neutral? (this is where a spice model would help because I could just try).
This looks like an optimal design -- I can't suggest any improvements
