Description

The BD555BKFV controller AC/DC controller IC can be used in a wide range of dimmable LED lighting driver applications. The main target application is dimmable retro-fit LED lighting, replacing existing incandescent light bulbs, halogen spot lights, CFL tubes etc.

Characteristics

  • Fixed frequency DC/DC controller (selectable)
  • Peak current or average current control (PCC/ACC)
  • Dynamic Load Current Controller (DLCC)
  • Logarithmic compensation of detected dimming level
  • Dimmer detector function
  • Anti-flash function when dimmer is OFF
  • PWM and analog dimming control supported
  • Over Current Protection (OCP)
  • Thermal Shutdown protection (TSD)
  • Under Voltage Lock Out (UVLO)
