This innovation is based largely, but not entirely,
on advances in magnetic materials,
and it didn’t come quickly.
Noted Jeff Morroni, director of power management research and development
at TI's Kilby Labs,
 
For example:
1.8 to 5.5V in to 5.5V out at 5.5A size 2.5 x 2.6 mm boost module

Their little SOT23 switcher chips are fabulous too. The TPS562208
costs us 22 cents, is rated for 2 amps, and runs spread-spectrum.

It's nice and quiet. We used some LTC integrated-inductor switcher
bricks that were EMI nightmares. I wish people would stop making their
n-channel substrate diodes into SRD's, which happens too often.
