PFC control IC reduces noise sensitivity for electronic ballast and SMPS
The IRS2500 µPFC controller can be configured to operate in critical conduction boost PFC or flyback configuration. The new device also 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.
Available in an SO-8 package, the IRS2500 also features micro power start up current of less than 50 µA, quiescent current of 2.5 mA, drive capability of +800 mA/-600 mA as well as static and dynamic over-voltage protection and over-current protection. The short minimum on time of the device allows wide input range power factor correction for universal input operation.
