Switch Mode Power Supply
Download the PDF catalogWhat it is?
Switch Mode Power Supply (SMPS) is a low cost flyback power supply base design that directly replaces multiples unregulated linear Power Supplies designs.
With extremely no-load low consumption, output efficency, and advanced safety features like over-voltage, over-current and thermal protection.
Our designs use the same format of encapsulated transformers, so it is suitable to use in the same PCB space. Worldwide universal input, several standard single or multiple ouptut voltages in different case formats.
