Overview

The HVLED001ATR is an offline controller designed for high-performance LED lighting applications using Quasi-Resonant (QR) topology. It features an integrated 800V high-voltage startup circuit and Primary Sensing Regulation (PSR) to provide high power factor and low total harmonic distortion (THD) without requiring an optocoupler for basic regulation. This controller supports multiple topologies including flyback, buck-boost, and SEPIC, making it versatile for various AC-DC LED driver designs.

Why Choose This Part

The device excels in efficiency by utilizing Quasi-Resonant switching to minimize power loss. It simplifies design with an 800V startup circuit that allows for fast turn-on times and reduced standby power consumption. Additionally, the Smart Auto-Reload Timer (ART) ensures latch-free operation during fault conditions, improving overall system robustness.

Applications

Commercial LED Lighting
High-efficiency drivers for office and industrial overhead lighting requiring high power factor and low THD.
Smart Lighting Systems
Utilizes the PWM dimming compatibility and remote control pin for integration into home automation networks.
Outdoor Luminaire Drivers
Reliable operation in street lighting or architectural lighting with an operating junction temperature up to 125 degrees Celsius.
Isolated Flyback Drivers
Provides accurate output voltage and current regulation using PSR mode to reduce component count and cost.

Getting Started

Designers should evaluate the HVLED001ATR using the STEVAL-ILL080V1 evaluation board, which demonstrates a flyback LED driver configuration. Ensure the VDD supply remains within the 8.8V to 16.5V range and leverage the programmable minimum off-time to optimize EMI performance.
