IR’s IRS2500 µPFC™ Control IC Reduces Noise Sensitivity for Cost Sensitive Electronic Ballast and SMPS Applications
EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the introduction of the IRS2500 µPFC™ power factor correction (PFC) control IC for switch mode power supply (SMPS), LED drivers, fluorescent and HID electronic ballast applications.
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.
“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,” said Peter Green, LED Group Manager, IR’s Energy Saving Products Business Unit.
Available in an SO-8 package, the IRS2500 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.
A datasheet and application note are available via the part number link above.
Availability and Pricing
Pricing for the IRS2500 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.
