Description

The IRS2500 is a fully integrated, fully protected PFC SMPS control IC designed to drive Boost or Flyback

switching regulators providing high power factor. Typical applications are PFC pre-regulators for SMPS and

electronic ballasts for fluorescent or HID lighting as well as single stage Flyback converters widely used in

low power LED drivers. The IRS2500 is pin compatible with most industry standard critical conduction or

transition mode PFC control IC with additional improvements to increase performance. The PFC circuitry

provides high PF, low THD and stable DC bus regulation over a wide line/load range. The IRS2500

protection features include cycle by cycle over-current protection and output over voltage protection.
