Overview
The HVLED001TR, produced by STMicroelectronics, is an enhanced peak current mode controller designed for high power factor (HPF) LED drivers. This controller is capable of controlling various topologies such as flyback, buck-boost, buck, boost, and SEPIC, with output power up to 150 W. It features a quasi-resonant (QR) topology and primary side regulation of output voltage, ensuring high efficiency and output stability across a wide voltage and current range.
The device incorporates advanced features like direct optocoupler connection for current loop regulation, high voltage start-up, and integrated input voltage detection for high power factor capability and protection triggering. It also includes a smart auto-recover timer (ART) to guarantee automatic application recovery without loss of reliability.
