HVLED001TR

Overview

The HVLED001TR is an offline LED lighting driver IC from STMicroelectronics, designed for high power factor flyback controllers with constant voltage primary sensing. It supports multiple topologies including boost, buck, flyback, and SEPIC. The device operates within a supply voltage range of 9.7V to 18V and features adjustable output voltage. It is housed in a 10-SSOP package and supports PWM dimming. The component functions as an AC/DC offline switch with one output and no internal switch, operating between -40°C and +125°C.

Feature Summary

• Enables direct connection to input voltage for startup and monitoring without external components
• Provides precise output voltage or current control using reduced passive component count
• Integrates smart auto-recover timer for automatic application recovery without reliability loss
• Supports 0-10 and PWM dimming compatibility with remote control pin functionality

Applications

• High power factor flyback LED drivers up to 150W
• Buck-boost topology LED lighting systems
• General purpose LED illumination applications

Procurement Notes

Verify the specific suffix (e.g., TR, ATR, BTR) against the required datasheet revision, as variants like HVLED001ATR and HVLED001BTR exhibit distinct electrical specifications such as supply voltage limits. Confirm RoHS3 compliance and moisture sensitivity level MSL 3 during sourcing. Ensure the selected variant matches the intended topology requirements, particularly regarding primary sensing capabilities and start-up voltage thresholds defined in the official documentation.

Selection Notes

Select this component for designs requiring high power factor and low total harmonic distortion in universal input ranges. Consider the 800V high voltage start-up capability for simplified circuitry. Evaluate the need for primary side regulation versus secondary sensing based on cost and accuracy requirements. The absence of an internal switch necessitates an external MOSFET selection aligned with the peak current mode control characteristics.
