2 posts / 0 new

Hi,
I am trying to design 15-1A dual isolated output SMPS using TNY280PN IC.
Could you help me with design and transformer construction details.

Hi Sriram,

Please refer to the design examples section in the tiny switch webpage. There is also an Applications section in the datasheet for giving design guidelines.

We recommend using our PIExpert tool to give a head start for the schematic and transformer design. It is a free tool.
