描述
The HIP6012EVAL1 evaluation board is used to evaluate the features of the HIP6012 buck and synchronous-rectifier pulse width modulator (PWM) controller.
The HIP6012 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 HIP6012 integrates all of the control, output adjustment, monitoring, and protection functions into a single package.
