The ADuM4470 / ADuM4471 / ADuM4472 / ADuM4473 / ADuM4474 are quad-channel, digital isolations with a regulated DC/DC isolated power supply controller with an internal MOSFET driver. The DC/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.The ADuM447x isolator provides a more stable output voltage and higher efficiency compared to unregulated isolated DC/DC power supplies. The fully integrated feedback and loop compensation in a wide-body SOIC package provide a smaller form factor and 8.3 mm creepage distance solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM3070 enables a DC/DC converter with a 3.3 V to 24 V isolated output voltage range from either a 5.0 V or a 3.3 V input voltage, with an output power of up to 2.5 W.The ADuM447x isolators provide four independent isolation channels in a variety of channel configurations and data rates. (The x in ADuM447x throughout this data sheet stands for the ADuM4470 / ADuM4471 / ADuM4472 / ADuM4473 / ADuM4474).
