ADP1071-1ARWZ-RL

Overview

The ADP1071-1ARWZ-RL is an isolated flyback controller manufactured by Analog Devices Inc. It operates within a switching frequency range of 50 kHz to 600 kHz and supports a maximum duty cycle of 85%. The device functions with a supply voltage between 4.7 V and 60 V, drawing a typical supply current of 22 mA. It is designed for operation across a temperature range of -40°C to +125°C and utilizes a 16-pin SOIC package.

Feature Summary

• Integrated synchronous rectification control for improved efficiency
• Light load management capabilities for reduced standby power consumption
• Galvanic isolation support for safety-critical applications

Applications

• Isolated flyback converter designs
• Forward converter topologies
• Industrial power supplies requiring high efficiency

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional compatibility. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the component meets required environmental specifications for the target operating temperature range before integration into final assemblies.

Selection Notes

Select this component when designing isolated power stages that require integrated synchronous rectification control. Evaluate the input voltage range requirements against the specified 4.7 V to 60 V limit. Consider the thermal performance within the 16-SOIC package relative to the expected power dissipation in the application environment.

Part Context

This part belongs to the ADP1071 family of isolated power controllers. It shares architectural similarities with variants like the ADP1071-2, which includes additional features such as secondary-side regulation. The series targets high-efficiency offline power conversion systems.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter alignment with any proposed replacement components.
