FR9809大電流降壓芯片代理商
詳情
Description
FR9809 is a high-efficiency synchronous step-down DC/DC converter that employs a special process technique to obtain very low RDS(ON) for the internal metal–oxide–semiconductor field-effect transistor (MOSFET). The input operation voltage is in a wide range from 4.75V to 21V, and continuous load current capability is 5A. Control circuit is designed by a particular current mode which provides fast transient response and eases loop stabilization.
This product has a very low standby current less than 1μA in shutdown mode. When the SHDN/S pin voltage is less than 0.4V, FR9809 will turn off. Fault protection includes over current protection (OCP), under voltage lockout protection (UVLO) and over temperature protection (OTP) function.
