Ever smaller DC-DC converter modules by TI:
 https://www.electronicdesign.com/technologies/power/article/55134121/electronic-design-tis-magnetic-materials-and-packaging-magic-help-slash-dc-dc-module-size-even-further
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
