SIMO DCDC buck boost

A single DCDC converter that can generate all the power supplies from a Li+ battery for a typical SoC or mixed signal IC. Typical output voltages include 5v, 4v, 3.3v, 1.8v, 1.2v, 0.9v, etc. The unique SIMO architecture enables the support of multiple outputs with a single inductor.
