I am looking for an ultra wide range universal AC-DC power supply and came across the DI-152 application using the TNY280 controller IC. However there are no line and load graphs showing what the expected performance is of the supply over the line and load ranges using the reference design. Can anyone provide some data? I'm currently coparing it to the only known competing solution from Ti that is based on the LM5022 that also achieves a similar input voltage range. However the output sag with the Ti solution is quite severe, dropping from 19V down to just 14V at low voltage DC in. That's only 73% load regulation at low input voltages and poses some significant design challenges.
I'm hoping the DI-152 design concept can provide some better load regulation performance, maybe 10% but I could not find any data on it. Thanks.
