DATASHEET
FN9035 Rev 1.
00 July 2004
The HIP6311A Multi-Phase Buck PWM control IC together with HIP6601A, HIP6602A or HIP6603A companion gate drivers form a precision voltage regulation system for advanced microprocessors.
The HIP6311A controls microprocessor core voltage regulation by driving 2 to 4 synchronous-rectified buck channels in parallel.
The multiphase buck topology takes advantage of interleaving phases to increase ripple frequency and reduce input and output ripp...
