TDA4863-2

概要

Fully compatible with the world standard, TDA4863-2 is optimized to offer extremely compact and cost effective PFC solutions for electronic ballast and off-line SMPS. By using a zero current detector for discontinuous operation mode a near unity power factor and an excellent THD are achieved.

特長

  • High power factor Power 
  •  Controls boost converter as active harmonic filter for low THD
  •  Start up with low current consumption
  •  Zero current detector for discontinuous conduction mode
  •  Output overvoltage protection
  •  Output undervoltage lockout
  •  Internal start up timer
  •  Totem pole output with active shut down
  •  Internal leading edge blanking LEB
  • Improvements of TDA48632 to TDA4862:
  •   Very low start up current
  •   Very low comparator and multiplier offsets for universal input applications
  •  High sophisticated amplifier for low distortion inteferences caused by MOSFET switching
  •  Accurate overvoltage threshold
  •  High gate drive capability (TDA48632 only)
