XR46073IHBTR

Overview

The XR46073IHBTR is a dual AC step driver controller designed for LED lighting applications. It operates within an input voltage range of 6 V to 76 V and supports output currents from 20 mA to 180 mA across two channels. The device features a TDFN-6 package and functions reliably between -40°C and +85°C. Key electrical specifications include a maximum supply current of 300 uA and a maximum power supply voltage of 76 V.

Feature Summary

• Integrated two-step driver with line regulation compensation
• Built-in thermal foldback protection
• VIN pin clamp functionality

Applications

• Replacing incandescent light bulbs
• LED lighting systems requiring dual AC step control

Procurement Notes

Verify component authenticity through authorized MaxLinear distributors or certified partners. Confirm the specific suffix IHBTR matches design requirements. Check for end-of-life status as indicated in official notifications. Ensure compliance with RoHS directives relevant to your region before integration into final products.

Selection Notes

Select this component for designs requiring dual-channel AC step driving with integrated thermal management. The TDFN-6 package suits space-constrained PCB layouts. Verify that the 76 V maximum input voltage aligns with the target AC source range. Consider the 300 uA quiescent current for low-power standby applications.

Part Context

This part belongs to the XR46000 series of LED drivers from MaxLinear. It is specifically engineered for high-efficiency AC-driven LED replacements. The series focuses on simplifying design by integrating driver and control functions into a single compact IC, reducing external component count.

Replacement Considerations

Check for direct substitutes within the XR46000 family. Verify pin compatibility and electrical parameters against existing designs. Consult MaxLinear documentation for approved cross-references.
