We have been using the PT5042A for some time to generate +15V from +8V.
The PTN04050C looks like a good replacement, but the input V range is 5.5V Max.
Is there an easy way to extend the input range to 8.5V on the PTN04050C?

Jim:
The absolute maximum input voltage is 5.5V. on PTN04050C. A preregulator could be added 8V to 5V on the input bus.
The discrete recommendatio is to use LM2700-adj or TPS61175.
There are other discrete designs available under WEB bench designs.
