HVLED001A：Offline controller for LED lighting with constant voltage primary-sensing and high power factor

The HVLED001A is an enhanced peak current mode controller capable of controlling high power factor (HPF) flyback or buck-boost topologies in LED drivers that have an output power of up to 150 W. Other topologies, such as buck, boost and SEPIC, can also be implemented.

ST’s innovative high voltage technology allows direct connection of the HVLED001A device to the input voltage to start up the device and to monitor the input voltage, without the need for external components.

The device embeds advanced features to control either the output voltage or the output current precisely and reliably using a reduced number of mainly passive components. Startup and light load conditions are managed by dedicated operating schemes to improve the quality of the regulation of the output variable in the final application. Abnormal conditions such as open circuit, output short-circuit, input overvoltage/ undervoltage and circuit failures like open loop and overcurrent of the main switch are effectively controlled.

A smart auto-recover timer (ART) function is built-in to guarantee automatic application recovery, without loss of reliability.
