ADP1048ARQZ-R7

Overview

The ADP1048ARQZ-R7 is an interleaved digital power factor correction (PFC) controller from Analog Devices. It utilizes continuous conduction mode PFC technology to reduce harmonic distortion and features a PMBus-compatible interface for real-time parameter adjustment and reporting. The device supports bridgeless boost modes to enhance efficiency and includes true RMS AC measurement capabilities for precise input voltage, current, and power monitoring.

Feature Summary

• Interleaved architecture reduces inductor size and solution footprint for high-power applications
• Flexible digital control loop optimizes harmonic correction and system efficiency
• True RMS AC measurement provides high-precision power metering functionality

Applications

• Communication infrastructure power systems
• Industrial motor control applications
• High-power medical imaging equipment

Procurement Notes

Verify the specific suffix ARQZ-R7 against the official datasheet to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm that the interleaved control logic aligns with the target system's electromagnetic interference constraints and efficiency targets before finalizing procurement.

Selection Notes

Select this component when designing high-efficiency AC/DC converters requiring digital flexibility and precise power metering. The interleaved topology is suitable for reducing passive component size compared to single-phase designs. Consider the integrated fault detection and programmable surge control features for enhanced system reliability in critical infrastructure environments.

Part Context

This part belongs to the ADP104x series of digital PFC controllers, which are designed for high-reliability power factor correction systems. It serves as the interleaved counterpart to the single-phase ADP1047, offering similar digital control benefits but with reduced magnetic component volume due to phase splitting.

Replacement Considerations

The ADP1047 is a related single-phase controller within the same family. Substitution requires evaluating whether the application necessitates the interleaved topology or if single-phase operation is sufficient.
