IRS2500S
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.
