FR9810
Description
FR9810 is a high-efficiency synchronous mode 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), with operation voltage in a wide 4.75V to 21V input voltage range. The output current is over 6A, and the efficiency is over 90%. Controller circuit design by a particular current mode operation provides fast transient response and eases loop stabilization.
This product has a very low standby current less than 1µA in shutdown mode. When the pin voltage is less than 0.4V, FR9810 will turn off the switching voltage regulator function and enter the standby mode. Fault protection includes current protect mode over current protection (OCP), voltage protect mode under voltage lockout protection
(UVLO), and internal thermal shutdown.
This high-efficiency current mode step-down “Green Power Converter” Fitipower offers the standard small-outline integrated...
