Datasheet HVLED001B (STMicroelectronics)

HVLED001B High power factor flyback controller with constant voltage primary-sensing and ultra-low standby consumption Datasheet - Production data Description
The HVLED001B is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost. Some other topologies such as buck, boost and SEPIC, can

also be implemented. Primary side regulation and optocoupler control can be applied independently on the chip, both
Features
exploiting precise regulation and very low standby power during no load conditions. Quasi resonant (QR) topology The innovative ST high voltage technology allows Primary side regulation of output voltage direct connection of the HVLED001B to the input Direct optocoupler connection for current loop voltage in order to both start up the device and to regulation with feedback disconnection monitor the input voltage, without the need for detection external components. 800 V high voltage startup Abnormal conditions like open circuit, output High power factor and low THD in universal short-circuit, input over-voltage or under-voltage range and circuit failures like open loop and overcurrent of the main switch are effectively controlled. High efficiency and output stability in wide voltage and current range A smart Auto Recover Timer (ART) function is Extremely low standby power at no load built in to guarantee an automatic application condition recovery, without any loss of reliability.
