XR46050IHBTR

Overview

The XR46050IHBTR is a two-step LED current controller designed for bulb applications powered directly by an AC voltage source. It features a single output capable of delivering 20 mA to 180 mA. The device operates within a supply voltage range of 6 V to 76 V and functions at temperatures from -40°C to +85°C. Packaged in a compact 6-DFN (TDFN-6) surface-mount format, it integrates driver functionality with improved line regulation and built-in thermal foldback protection.

Feature Summary

• Two-step integrated driver architecture for direct AC input
• Built-in thermal foldback and VIN pin clamp for enhanced reliability
• Improved line regulation characteristics
• Eliminates the need for electrolytic capacitors

Applications

• Replacing incandescent light bulbs
• LED lighting driver ICs
• Solid-state lighting systems

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official documentation. Validate package integrity upon receipt. Ensure storage conditions meet manufacturer specifications to prevent degradation. Cross-reference datasheet revisions for accurate electrical parameters before integration.

Selection Notes

Select this component for designs requiring direct AC drive without external rectification stages. Consider the TDFN-6 package for space-constrained PCB layouts. Evaluate thermal management requirements given the integrated foldback feature. Verify input voltage compatibility with the 6 V to 76 V operating range. Assess output current needs against the 20 mA to 180 mA specification.
