PRESS RELEASE IRS2500 µPFC™ Control IC Reduces Noise Sensitivity for Cost Sensitive Electronic Ballast and SMPS Applications DATA SHEET HI-RES GRAPHIC The IRS2500 µPFC™ power factor correction control IC is suitable for switch mode power supply (SMPS), LED drivers, fluorescent and HID electronic ballast applications. Lighting HOME PAGE 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 (<50µA) 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 IR’s 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. November 2011
