HVLED001A

Overview

The HVLED001A is an offline controller for LED lighting featuring constant voltage primary-sensing and high power factor. It supports quasi-resonant flyback topologies with a wide input voltage range of 180 VAC to 264 VAC. The device delivers an output current of 200 mA and operates within a temperature range of -40°C to +125°C. It utilizes a 10-SSOP package and includes protection mechanisms for open circuit, short circuit, undervoltage, and overvoltage conditions.

Feature Summary

• Integrates high voltage startup technology allowing direct connection to input voltage without external components.
• Provides precise output voltage or current regulation using a reduced number of passive components.
• Features smart auto-recover timer function to guarantee automatic application recovery without reliability loss.
• Manages startup and light-load conditions through dedicated operating schemes for improved variable regulation.

Applications

• High power factor flyback LED drivers
• Buck-boost topology LED drivers
• Offline LED lighting systems up to 150 W

Procurement Notes

Verify the specific ordering suffix (e.g., TR) against the manufacturer's official datasheet to confirm tape-and-reel packaging requirements. Ensure the component matches the exact pinout and electrical specifications defined in the latest public documentation before integration into the design.

Selection Notes

Select this controller for applications requiring primary-side sensing to minimize component count. It is suitable for designs needing high power factor correction and robust protection features. Consider the thermal performance limits when designing for the upper end of the specified operating temperature range.

Part Context

This component belongs to STMicroelectronics' family of offline controllers designed specifically for LED illumination. It complements evaluation boards such as the STEVAL-ILL080V1, which demonstrates its use in 18 W tube replacement drivers. The part serves as a core control element for efficient and reliable power conversion in solid-state lighting.
