HVLED001B High Power Factor Flyback Controller

STMicroelectronics HVLED001B High Power Factor Flyback Controller is an enhanced peak current mode controller able to control mainly High Power Factor (HPF) Flyback or Buck-Boost. The HVLED001B can also be used to implement other topologies such as Buck, Boost, and SEPIC. Primary side regulation and optocoupler control can be applied independently with the HVLED001B, both exploiting precise regulation and very low standby power during no-load conditions. ST High Voltage Technology allows direct connection of the HVLED001B to the input voltage in order to both start up the device, and to monitor the input voltage, without the need for external components. The HVLED001B includes protection against abnormal conditions, including open circuit, output short-circuit, input over-voltage, and under-voltage. Circuit failures like open loop and overcurrent of the main switch are also effectively controlled. The STMicroelectronics HVLED001B High Power Factor Flyback Controller also integrates an Auto Recover Timer (ART) function to guarantee an automatic application recovery, without any loss of reliability.
