We have used the LM3420-16.8 in an application for many years. That 16.8V set voltage version got obsoleted, only the 8.4V version is available. The data sheet still says one can use this device for 1,2,3 or 4 cells. How do I do that? My problem is that it is used in a UL listed device, so i don't want to change the overall circuit, if possible.
Thanks,
Chris
