ADUM4070ARIZ-RL

Overview

The ADUM4070ARIZ-RL is a 5kV isolated switch regulator with integrated feedback, manufactured by Analog Devices Inc. It operates in a push-pull topology within an SOIC-16 package. The device accepts an input voltage range of 3 V to 5.5 V and provides a regulated output voltage between 3.3 V and 24 V. It delivers a maximum output current of 500 mA with a switching frequency of 1 MHz. Static current consumption is specified at 4 mA, and load regulation is rated at 1%. The component functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a 5kV digital isolator with a DC/DC converter for complete isolation
• Provides regulated isolated power supply with internal feedback loop
• Supports high-speed switching at 1 MHz for compact magnetic design

Applications

• Isolated power delivery in industrial automation systems
• Power supply modules for medical equipment requiring galvanic isolation
• Interface circuits in automotive electronic control units
• Signal conditioning boards in process control instrumentation

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability records. Check for moisture sensitivity level requirements during storage. Validate that the received part matches the exact manufacturer number before integration.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. The integrated feedback simplifies design compared to separate isolator and converter solutions. Consider the 500 mA output capability against system load requirements. Evaluate the 1 MHz switching frequency impact on external inductor selection. Verify input voltage compatibility with the 3 V to 5.5 V operational range.
