FR9806 Description
FR9806 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 4.75V to 21V, and continuous load current capability is 3A. Control circuit is designed by a particular current mode which provides fast transient response and eases...
