Description
General part information
ADUM4070 Series
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 feedback and compensates the loop for stability.The ADuM4070 isolator provides 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 solution with a smaller form factor and 8.3 mm creepage distance.The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM4070 enables a dc-todc 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..ApplicationsPower supply startup bias and gate drivesIsolated sensor interfacesProcess controls
