ADP1071-1ACCZ-R7

Overview

The ADP1071-1ACCZ-R7 is an isolated flyback controller manufactured by Analog Devices Inc. It features a 24-pin LGA package and supports a switching frequency range of 50 kHz to 600 kHz with a maximum duty cycle of 85%. The device operates within an input voltage range of 4.5 V to 36 V, drawing a typical quiescent current of 16.6 mA and a maximum supply current of 3.8 mA. It functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates iCoupler technology for galvanic isolation in feedback paths
• Supports synchronous rectification for improved efficiency
• Includes programmable soft-start functionality

Applications

• Isolated power supplies
• Flyback converters
• Forward converters

Procurement Notes

Verify the specific suffix ACCZ against official documentation to confirm the tray packaging format. Confirm availability status as distribution channels may list limited stock or discontinuation notices. Ensure the reel variant matches design requirements if tape-and-reel handling is necessary.

Selection Notes

Select this component for designs requiring integrated isolation without external optocouplers. Evaluate thermal performance within the specified operating temperature range. Verify that the 24-pin LGA footprint aligns with PCB layout constraints and assembly capabilities.

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 configuration and specific feature sets tailored for single-output applications.

Replacement Considerations

Cross-reference with ADP1071-2ACCZ for similar topology support. Verify functional compatibility regarding control loops and isolation barriers before substitution.
