Other Parts Discussed in Thread: LM5155
Hello team,
I need to check what is the highest boost ratio when use LM5155 as Sepic topo.
In the datasheet, when RT=220k,
if Dmax=90% (min), the boost ratio is 9,
if Dmax=93% (typical), the boost ratio is 13.3,
if Dmax=94% (max), the boost ratio is 24.
The boost ratio range greatly under different Dmax value, so they want to confirm is it safe to continues work under boost ratio=24 when power is about 15-20W, and what is the recommended maximum boost ratio?
Thanks!
