Control IC reduces noise sensitivity, targets SMPS applications
1 min read
International Rectifier has introduced the IRS2500 µPFC power factor correction control IC for switch mode power supply (SMPS) applications, led drivers and fluorescent and HID electronic ballast applications.
The controller can be configured to operate in critical conduction boost pfc or flyback configuration. It can also feature a total harmonic distortion optimisation circuit to reduce line current harmonics. The controller is said to have 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 features micro power start up current of less than 50µA, quiescent current of 2.5mA, drive capability of +800mA/-600mA and static and dynamic over voltage protection and over current protection. According to IR, the short minimum on time of the device allows wide input range power factor correction for universal input operation.
