International Rectifier, IR, (NYSE: IRF), a world leader in power management technology, today announced the introduction of the IRS2500S μPFC™ power factor correction (PFC) control IC for switch mode power supply (SMPS), LED drivers, fluorescent and HID electronic ballast applications. The IRS2500S 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. "The IRS2500S 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," said Peter Green, LED Group Manager, IR's Energy Saving Products Business Unit. Available in an SO-8 package, the IRS2500S also features micro power start up current of less than 50μA, quiescent current of 2.5mA, drive capability of +800mA/-600mA 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 Design Tools A datasheet and application note are available on the International Rectifier website. Availability and Pricing Pricing for the IRS2500S begins at US $0.33 each in quantities of 10,000-units. Production quantities are available immediately. The devices are lead free and RoHS compliant. Prices are subject to change. About International Rectifier International Rectifier (NYSE:IRF) is a world leader in power management technology.
