GENERAL DESCRIPTION

The ADuM4470/ADuM4471/ADuM4472/ADuM4473/ADuM4474 are quad-channel, digital isolators with a regulated dc-to-dc isolated power supply controller and an internal MOSFET driver. The dc-to-dc controller has an internal isolated PWM feedback from the secondary side, based on the iCoupler® chip scale transformer technology and complete loop compensation. This eliminates the need to use an optocoupler for feedback and compensates the loop for stability.
