... Data Sheet Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller 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 synchronous-rectified buck channels in parallel ...
