DESCRIPTION

· IRS2500SPBF is a Transition Mode PFC Control IC designed for Boost PFC applications.

· It supports a wide input range for universal AC line input and operates in critical-conduction/transition mode.

· The IC features voltage mode control and includes protections such as static and dynamic DC output over-voltage protection, cycle by cycle over-current protection, and latch immunity with ESD protection.

· It also offers micro-power startup (<50µA) and low quiescent current, making it efficient for various power supply applications.
