ADUM6000: An Introduction to Isolated 5 kV DC/DC Converters

The ADuM6000 is an isolated DC/DC converter based on Analog Devices, Inc., iCoupler® technology. This DC/DC converter provides regulated isolated power for a variety of input/output voltage combinations, as listed in Table 1 of the data sheet. Analog Devices, Inc., chip-scale transformer iCoupler technology enables this DC/DC converter to achieve up to 31% efficiency in isolated power transfer, thus providing a small form factor, fully isolated solution. Using the ADuM6000, higher output power levels can be achieved over the iCoupler family of isolators, the ADuM5401, ADuM5402, ADuM5403, ADuM5404, ADuM520x, and ADuM620x. isoPower® utilizes high frequency switching elements to transfer power through its transformer. Special attention must be paid to meeting radiated emissions standards during printed circuit board (PCB) layout. For board layout recommendations, refer to Application Note AN-0971.
