Overview
The ADUM4070ARIZ is a 5kV isolated switch regulator with integrated feedback, manufactured by Analog Devices Inc. It operates within an input voltage range of 3 V to 5.5 V and delivers up to 500 mA output current. The device supports output voltages from 3.3 V to 24 V and functions at a switching frequency of 1 MHz. It utilizes a push-pull topology in a 16-lead SOIC package. The component maintains a static current of 4 mA and ensures 1% load regulation. It is rated for operation between -40°C and +105°C.
Feature Summary
- Integrates isolation barrier with power conversion to eliminate external optocouplers
- Provides precise closed-loop regulation via integrated capacitive feedback channel
- Utilizes iCoupler magnetic coupling technology for high common-mode transient immunity
Applications
- Industrial control systems requiring galvanic isolation
- Medical equipment power supplies
- Data acquisition modules
- Inverter and motor drive circuits
Procurement Notes
Verify the specific suffix 'ARIZ' against official Analog Devices documentation to confirm temperature grade and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Ensure ESD handling protocols are followed during installation due to moisture sensitivity classification.
Selection Notes
Select this component when simultaneous signal isolation and isolated power delivery are required in a compact form factor. Evaluate the 500 mA output capability against system load requirements. Consider the 1 MHz switching frequency for thermal management and passive component selection. Verify that the 5 kV isolation rating meets safety standards for the target application environment.
Part Context
This part belongs to the ADUM4070 series of IsoPower isolated DC-to-DC converters. It combines a switcher controller with a digital isolator on a single chip. The series is designed to simplify designs by reducing component count compared to traditional solutions using separate isolators and regulators.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications before implementation.
