ADP1071-1ARWZ

Overview

The ADP1071-1ARWZ is an isolated flyback controller from Analog Devices, designed for high-efficiency power conversion. It features a switching frequency range of 50 kHz to 600 kHz and supports a maximum duty cycle of 85%. The device operates within a supply voltage range of 4.7V to 60V and draws a typical supply current of 22 mA. It is housed in a 16-SOIC surface-mount package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates iCoupler technology for galvanic isolation without requiring external optocouplers
• Supports synchronous rectification to enhance converter efficiency
• Features programmable switching frequency for flexible design optimization

Applications

• Isolated flyback converters
• Forward converters
• LED lighting power supplies

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required packaging configuration. Ensure compliance with RoHS standards and check for any product change notifications that may affect specifications or availability before finalizing procurement plans.

Selection Notes

Select this controller for designs requiring high isolation integrity and reduced component count. The integrated digital isolation eliminates optocoupler latency issues. Evaluate thermal performance requirements against the specified operating temperature range. Consider the SOIC-16 footprint constraints during PCB layout planning to ensure adequate spacing and heat dissipation.

Part Context

This part belongs to the ADP1071 family of isolated DC-DC controllers. It shares core architecture with variants like the ADP1071-2 series but differs in pinout and specific feature configurations. The family targets efficient offline power supply applications using proprietary coupling technology.

Replacement Considerations

Direct substitutes include the ADP1071-2ARWZ-R7 for reel-packaged versions. Verify functional compatibility regarding control logic and pin assignments when considering alternative packages or suffixes within the same product line.
