AS1454 Design Feature in Power Electronics Technology – Oct 2009

Digital Power SoC offers 92% Efficiency to Isolated Designs

by Sam Davis, Editor in Chief

Intended for applications such as industrial, datacom, automotive, medical, residential gateway, and display, an isolated quad-output digital-power SoC from Akros Silicon Inc. suits isolated power designs. As shown in Fig. 1, the AS14x4 integrates a 2-kV isolation barrier and a wide-input-range (9 to 72 V) isolated primary converter to enable its use in 12/24-Vdc, 24-Vac distributed, and 48-V distributed-power applications requiring a 36- to 72-V input voltage range.
