ADUM3070ARQZ Datasheet PDF - ADI

●The ADUM3070 series Isolated Switching Regulator with integrated feedback. It 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 regulated feedback provides a relatively flat efficiency curve over the full output power range. It enables a DC-to-DC converter with a 3.3 to 24V isolated output voltage range from either a 5 or a 3.3V input voltage, with an output power of up to 2.5W.
