The HP1011 is a digital dual-phase interleaved PFC controller(DIPFC) operating in multiple modes. HP1011 supports two current sense schemes,either current transformer or resistors as your design may require. Phase shedding can be realised with any of the two channels without restrictions. Further flexibility to symmetrize the current of two channels is also available with simple register settings. Communicating through I2C and UART interface,the entire design process is rather intuitive thanks to a Graphic User Interface(GUI) developed by Hynetek.Housed in a 4 mm x 4 mm QFN-24 package, HP1011 is the ultimate choice of a global platform design, supporting both high/low AC lines and HVDC operations.
