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 all 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 protection (OCP) monitors the voltage drop across the RDS(ON) of the lower MOSFET for synchronous buck PWM DC-DC controller. The overcurrent function cycles the soft-start in 4-times hiccup mode to provide fault protection, and in an always
