HIP6002CB中文资料INTERSIL数据手册PDF规格书

Rectifier (PWM) Controller and Output Voltage Monitor

The HIP6002 provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The HIP6002 integrates all of the control, output adjustment, monitoring and protection functions into a single package.
