ADUM3070ARQZ

ADUM3070 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 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. It 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 provides a smaller form factor than any discrete solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. It is used in applications such as power supply start-up bias and gate drives, isolated sensor interfaces, process controls.
