Comm Equip Makers Demand High Power Output & Small Footprint

Tony Armstrong Marketing Director, Power Products Analog Devices, Inc.

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
