HVLED001A Offline controller for LED lighting with constant voltage primary- sensing and high power factor Datasheet - production data Description 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 SSO10 SEPIC, can also be implemented. STs innovative high voltage technology allows direct connection of the HVLED001A device to Features the input voltage to start up the device and to Quasi resonant (QR) topology monitor the input voltage, without the need for external components. Optimized output voltage accuracy at any load (PSR mode) The device embeds advanced features to control Improved transient response and startup time either the output voltage or the output current precisely and reliably using a reduced number of Direct optocoupler connection for current loop mainly passive components. Startup and light regulation with feedback disconnection load conditions are managed by dedicated detection operating schemes to improve the quality of the 800 V high voltage startup regulation of the output variable in the final High power factor and low THD over wide application. Abnormal conditions such as open range of input voltage and load variations circuit, output short-circuit, input overvoltage/ undervoltage and circuit failures like open loop High efficiency and output stability over wide and overcurrent of the main switch are effectively voltage and current range controlled. Low startup and quiescent current A smart auto-recover timer (ART) function is built- Programmable minimum off-time in to guarantee automatic application recovery, Integrated input voltage detection for high without loss of reliability. power factor capability and protection triggering Table 1.
