Comm Equip Makers Demand High Power Output & Small Footprint

Figure1. LTM4622(A) Can Be Mounted on the Underside of a PCB

Many communications systems are powered via a 48V backplane. This voltage is normally stepped down to a lower intermediate bus voltage, typically to either 12V, 5V or even lower, in order to power the racks of boards within the system. However, most of the sub-circuits or ICs on these boards are required to

Nanomachine Swarms Could Improve Efficiency of any Machine

Density plot of the power output of an energy-converting network that consists of interacting nano-machines illustrated by the spheres. The power increases from red to blue color, thus in the synchronization phase corresponding to the area enclosed by the white dashed lines, the output of the network is maximized.

All machines convert one form of energy into another form - for example a car engine turns the energy stored in fuel into motion energy. Those processes of energy conversion, described by the theory called thermodynamics, don't only take place on the macro-level of big machines, but also at the micro-level of
