General  Descript ion

The RT9214 is a high efficiency synchronous buck PWM controllers that generate logic-supply voltages in PC based systems. These high performance , single output devices include internal soft -start, frequency compensation networks and integrates al   of  the control ,  output adjustment, monitoring and protection functions into a single package.
The device operating at fixed 300kHz frequency provides an optimum compromise between efficiency, external component size, and cost. Adjustable over-current protect ion (OCP) monitors the voltage drop across theRDS(ON) of  the lower MOSFET for synchronous buck PWM DC/DC controller.  The over current  function cycles the soft-start in 4-times hiccup mode to provide fault protection, and in an always hiccup mode for under-voltage protection.
