The STNRGPF12 digital controller is designed for interleaved PFC boost topologies and intended for use in high power applications.It features a digital inrush current control implemented with a solid state solution based on a silicon controlled rectifier. The controller can drive up to 2 interleaved channels.The device works in CCM at fixed frequency with average current mode control, in applications based on a mixed signal (analog/digital) architecture.The controller can be configured through a dedicated software tool (eDesignSuite) to match a wide range of specific applications. The tool generates a full schematic including a complete list of material and the final binary object code (FW) to be downloaded to the IC.
