GENERAL DESCRIPTION The ADuM50001 is an isolated DC/DC converter. Based on Analog Devices’ iCoupler® technology, the DC/DC converter provides up to 500 mW of regulated, isolated power at either 5.0V from a 5.0V input supply or 3.3V from a 3.3V or 5.0V supply. Analog Devices’ chip-scale transformer iCoupler technology is used both for the DC/DC converter. The result is a small form-factor total-isolation solution. ADuM5000 units may be used in combination with ADuM540x and ADuM520x with isoPower to achieve higher output power levels. Rev. PrA Information furnished by Analog Devices is believed to be accurate and reliable. How...
