HVLED001ATR

Overview

The HVLED001ATR is an offline controller for LED lighting featuring constant voltage primary sensing and high power factor capabilities. It supports flyback, buck-boost, buck, boost, and SEPIC topologies with output power up to 150 W. The device utilizes 800 V high voltage startup technology for direct input connection without external components. It offers one output in a 10-SSOP package, operating within a temperature range of -40°C to +125°C. Maximum supply voltage is 16.5 V, with adjustable output voltage and 600 mA output current capability.

Feature Summary

• Supports quasi-resonant topology with primary side regulation for precise output voltage control
• Enables direct optocoupler connection for current loop regulation with feedback disconnection detection
• Integrates smart auto-recover timer (ART) function to guarantee automatic application recovery without loss of reliability
• Compatible with 0-10 and PWM dimming standards for flexible lighting control

Applications

• Offline LED lighting drivers requiring high power factor
• Flyback or buck-boost topology implementations for output power up to 150 W
• Buck, boost, and SEPIC topology LED driver designs
• Applications requiring remote control pin functionality

Procurement Notes

Verify the specific suffix 'ATR' against the official STMicroelectronics datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the active status indicated for the HVLED001A series rather than the obsolete HVLED001 base model. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and compliance with RoHS3 standards before procurement.

Selection Notes

Select this controller for designs requiring high power factor and low total harmonic distortion across universal input ranges. The integrated 800 V startup technology reduces external component count by eliminating bias winding requirements. Consider the programmable minimum off-time and latch-free operation for improved stability in wide voltage and current ranges. Ensure the design accommodates the 10-SSOP package constraints and thermal management requirements for the specified operating temperature range.

Part Context

The HVLED001ATR belongs to the HVLED001A series of offline controllers designed specifically for LED lighting applications. This series represents an enhancement over the original HVLED001, offering optimized output voltage accuracy at any load in PSR mode and improved transient response. The device is manufactured by STMicroelectronics and is categorized under LED driver ICs for AC/DC offline switching applications.

Replacement Considerations

The original HVLED001 is listed as obsolete; the HVLED001A series serves as the functional successor. Verify pinout compatibility and parameter alignment between the legacy HVLED001 and the HVLED001A series when transitioning designs. No other public substitute part numbers are confirmed in the provided documentation.
