RT9214全新原装现货，***赔十13724201506李生。***:2629331408.The RT9214 is a high efficiency synchronous *** 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 functi*** 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 ***(ON)of the lower MOSFET for synchronous *** 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.
