A concept of lithium and oxygen compounds encased in a lattice of cobalt oxide – the chemical energy generator that powers a novel lithium-oxygen electric car battery (MIT via Nature) Researchers at MIT, Argonne National Laboratory, and Peking University may have found a way to overcome the challenges of the lithium-air battery. The new technology is more lightweight batteries with twice the charge, and could be market ready as early as next year.   There’s no denying the impac ...
I received an evaluation board for the TPS54A20 DC/DC converter from TI. This switcher is specific for low voltage designs. The output range is 0.5 - 2 V. That's a very narrow range. In that range it can deliver 10 A, with a typical input of 12 V. Efficiency is in the lower-to-mid 80%. With a switch frequency of 2 MHz (more on that later) it allows for small passive components and a condensed footprint of the whole stepdown module.   The reason that I want to review this particular c ...
