HVLED001BTR

Overview

The HVLED001BTR is an LED driver IC featuring a high power factor flyback controller with constant voltage primary sensing. It supports multiple topologies including boost, buck, flyback, and SEPIC. The device operates on a single output with adjustable voltage. Supply voltage ranges from 7.3V to 18V. It functions within a temperature range of -40°C to +125°C TJ. The component utilizes PWM dimming and is housed in a 10-SSOP package.

Feature Summary

• Integrates high voltage technology for direct connection to input voltage without external startup components
• Provides precise regulation and ultra-low standby power during no-load conditions via primary side regulation
• Includes built-in Auto Recover Timer (ART) for automatic application recovery without reliability loss
• Effectively controls abnormal conditions such as open circuit, output short-circuit, and overcurrent

Applications

• High power factor flyback converters for LED lighting systems
• Buck-boost topology implementations for general illumination
• Offline controllers requiring low standby consumption
• Designs utilizing primary side regulation to eliminate optocouplers

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as variations exist between reel, cut tape, and Digi-Reel options.
