GENERAL DESCRIPTION
The ADuM4470/ADuM4471/ADuM4472/ADuM4473/
ADuM44741 are quad-channel, digital isolators with a regu- lated 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 compen-
sation. This eliminates the need to use an optocoupler for
feedback and compensates the loop for stability.
The ADuM447x isolators provide a more stable output voltage
and higher efficiency compared to unregulated isolated dc- to-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 ADuM447x enable a dc-
to-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.)
