I've seen these before but never used them due to the cost.  There
are some other options such as reducing the battery voltage and using
a low dropout regulator such as the LM2941.  Then there isn't very
much energy to turn into heat.  If the battery voltage dips much, then
the thing wouldn't work.  There are also some "simple switcher" chips
that can be used in addition to some external components including
inductors.

Roger.
