This is one of the all time worst electronic engineering books I have ever encountered. A few minutes searching the Maxim web site will find most of the material. 90% of the examples are simply reprints from Maxim data sheets, or Maxim app. notes and engineering handbooks. Most of the material is out of date, even allowing for the book being 10 years old. It does not cover modern battery technologies (such as LiIon, or LiPoly), and does not really cover any of the "stuff" other than the switching supply itself. Notable by not being there would be any material on micropower processors, logic, interfacing across logic families, latchup, linear peripherals, low power switching, protection, design techniques, measurements, and a host of others.A better title might have been "Some out of date Maxim medium power Switcher Datasheets briefly explained".Sorry John -- you have published some good work, but this isn't it.
