CEATEC2013-17 e A4 (210mm×297mm)
Distributed Power Architecture (DPA)
CEATEC2013-17
Decisive solution for efficiently providing power to various
applications, further enhanced by digital control
ICT infrastructure equipment used for transmitting, sharing, and storing information is becoming ever more widespread. Semiconductor devices in
such equipment must operate at low voltages while handling large currents and supporting high-speed operation. This is normally realized by
positioning power supplies in close proximity to load devices, a technique known as Distributed Power Architecture (DPA). By adopting digital
control, DPA solutions from TDK enable the realization of more compact and efficient systems, further enhanced by support for versatile functions
via the PM-Bus communication interface. This ensures stable voltage and power supply to high-performance CPUs. In recent years, DC power
supply systems are being increasingly implemented also in industrial equipment and measuring equipment. TDK power modules can contribute
to smaller dimensions, high reliability, and high-density mounting through fanless design, water-cooling, and hermetically sealed construction.
