ADP1071-2ARWZ-R7

Overview

The ADP1071-2ARWZ-R7 is an isolated flyback controller with integrated synchronous rectification, manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.7V to 60V and draws a typical supply current of 22 mA. The device supports switching frequencies from 50 kHz to 600 kHz and features a maximum duty cycle of 85%. Designed for surface mount installation in a 16-SOIC package, it functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates primary-side regulation with synchronous rectification control
• Supports flyback and forward converter topologies
• Features adjustable switching frequency up to 600 kHz

Applications

• Isolated flyback power supplies
• Forward converter designs
• LED lighting drivers requiring isolation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches the required reel packaging configuration. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Validate that the procurement source provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this controller for applications requiring high efficiency via synchronous rectification without optocouplers. Consider the 16-SOIC package for space-constrained PCB layouts. Evaluate the input voltage range against the specific transformer design requirements. Ensure the thermal performance meets the operational environment constraints.

Part Context

This component belongs to the ADP1071 family of isolated controllers. It complements variants like the ADP1071-1ARWZ-R7 which lacks integrated synchronous rectification. The series targets efficient isolated power conversion solutions.

Replacement Considerations

The ADP1071-2ACCZ serves as a tray-packaged alternative within the same functional family.
