The ADuM5000 is an isolated DC/DC converter based on the Analog Devices, Inc., iCoupler® technology. The DC/DC converter in this device provides regulated, isolated power in several combinations of input and output voltage as listed in Table 1.
The Analog Devices chip-scale transformer iCoupler technology transfers isolated power in this DC/DC converter with up to 33% efficiency. The result is a small form factor, total isolationsolution.
Higher output power levels are obtained by using the ADuM5000 to augment the power output of ADuM5401, ADuM5402, ADuM5403, ADuM5404, and ADuM520x iCouplers with isoPower®.
isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissionsstandards. Refer to the AN-0971 application note for board layout recommendations.
