ADUM3070ARQZ-RL7

Overview

The ADUM3070ARQZ-RL7 is an isolated switching regulator with integrated feedback, manufactured by Analog Devices Inc. It operates within a 3 V to 5.5 V input voltage range and provides adjustable output voltages from 3.3 V to 24 V. The device supports output currents of 350 mA and 500 mA across two outputs. It features a switch frequency ranging from 200 kHz to 1 MHz and functions in push-pull topology. The component is housed in a 16-QSOP package and operates between -40°C and +105°C.

Feature Summary

Integrates magnetic coupling for signal and power transmission across isolation barriers
Includes internal feedback loop to regulate output voltage without external optocouplers
Supports adjustable output voltage settings via external resistor networks
Provides galvanic isolation between primary and secondary sides

Applications

Industrial control systems requiring isolated power supplies
Medical equipment needing certified isolation barriers
Test and measurement instruments with high-voltage isolation requirements
Automotive electronics utilizing isolated DC-DC conversion

Procurement Notes

Verify the complete part number including the RL7 suffix to confirm reel packaging configuration. Ensure compatibility with QSOP-16 footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when design requirements demand integrated isolation feedback to reduce bill of materials complexity. Evaluate thermal performance under maximum load conditions given the 350 mA to 500 mA output capability. Consider the 200 kHz to 1 MHz switching frequency range for electromagnetic interference management in sensitive environments.

Part Context

This part belongs to the ADuM3070 series of isolated switching regulators. It utilizes Analog Devices' iCoupler technology for magnetic signal and power transfer. The series is designed to replace traditional transformer-based solutions with optocoupler feedback loops in compact form factors.
