GENERAL DESCRIPTION
The ADu M30701 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 i Coupler® chip scale transformer technology and plete loop pensation. This eliminates the need to use an optocoupler for feedback and pensates the loop for stability.
