• Features
• PFC Control IC
• Boost or Flyback Converter Modes
• Critical-conduction/transition mode operation
• Over-current protection
• Static and dynamic DC bus overvoltage protection
• Micropower startup (lt50µA)
• Low quiescent current (2.5mA)
• Latch immunity and ESD protection
• Wide range PFC for universal AC line input
• Lower THD
• Open load over voltage protection
• Noise immunity

• Advantages
• The IRS2500 µPFC controller can be configured to
  operate in critical conduction boost PFC or
  flyback configuration.
• The device features a total harmonic distortion
  (THD) optimization circuit to reduce line current
  harmonics.
• The controller has high noise immunity
  simplifying design and reducing system cost.
• The IRS2500 PFC control IC expands IRs existing
  SMPS and general lighting device portfolios.
  The new device reduces noise sensitivity, eases
  PCB layout and provides a cost effective
  alternative to existing solutions.
