The STNRGPF02 / STNRGPF12 is a digital controller designed specifically for interleaved PFC boost topologies and intended for use in high power applications.

The STNRGPF02 offers traditional inrush current control implemented with mechanical solution based on a relay and limiter resistor.

The STNRGPF12 features a digital inrush current control implemented with a solid state solution based on a silicon controlled rectifier.

The controller is capable of driving 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 will generate a full schematic which includes a complete list of material and the final binary object code (FW) to be downloaded to the IC.
