HVLED001B Flyback Controller

STMicro's high power factor flyback controller with constant voltage primary-sensing and ultra-low standby consumption

Image of STMicro's HVLED001B Flyback ControllerSTMicro's HVLED001B is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost topologies in LED drivers having an output power up to 150 W. Primary side regulation and optocoupler control can be applied independently on the chip both exploiting precise regulation and very low standby power during no load conditions.

The innovative ST high voltage technology allows users to directly connect the HVLED001B to the input voltage in order to both start-up the device and monitor the input voltage without the need of external component.

Features
  • Constant voltage (CV) output regulation with no optocoupler
  • 800 V embedded high voltage startup circuitry
  • Quasi-resonant operation
  • Fast startup: <350 ms
  • Feed forward compensation
  • Low power consumption
Benefits
  • Reduce the number of external components
  • High reliability
  • High efficiency due to zero voltage switching operation
  • Fast IC startup
  • Output current regulation independent from mains variation
  • It is possible to respect no-load power requirements
