APPLICATIONS Power supply start-up bias and gate drives Isolated sensor interfaces Process controls www.DataSheet.net/ GENERAL DESCRIPTION The ADuM40701 is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver. The dc-to-dc controller has internal isolated PWM feedback from the secondary side based on the iCoupler® chip scale transformer technology and complete loop compensation. This architecture eliminates the need to use an optocoupler for ...
