Switch Mode Power Supply

I need a power supply for a small device we've developed.

We can't use the traditional transformer, bridge rectifier, regulator method as we dont have the space.

I need a really small power supply (transformerless or switch mode) to give me 12v output and 1amp current.


Input voltage: 240vac

output voltage: 12vdc

output current: 1amp

Small footprint

Thermally stable.

Skills: Circuit Design, Electrical Engineering, Electronics, Engineering, PCB Layout
