The STNRGPF01 is a digital controller designed specifically for interleaved PFC boost topologies and intended for use in high power applications.

The controller is capable of driving up to 3 interleaved channels, generating the proper signals in each condition. Moreover, it implements a flexible phase shedding strategy that enables the correct number of PFC channels based on the actual load condition. With this function, the STNRGPF01 is always able to guarantee the highest power efficiency across a wide range of load current requirements.

It is configured through the eDesignSuite tool.
