Description
General part information
ADUM3070 Series
The ADuM3070 isolator is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver. The dc-to-dc controller has an internal isolated PWM feedback from the secondary side based on theiCoupler®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 ADuM3070 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 small QSOP package provides a smaller form factor than any discrete solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM3070 enables 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.APPLICATIONSPower supply startup bias and gate drivesIsolated sensor interfacesProcess controls
