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.
