资 源 简 介
The ADuM30701 isolator is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver. The dc-todc 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 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.
