NCP5425 Dual Synchronous Buck Controller
The NCP5425 is a highly flexible dual buck controller with internal
gate drivers that can be used with two input power supplies and one or
two outputs in multiple configurations. The part contains all the
circuitry required for two independent synchronous dual NFET buck
regulators utilizing a feed forward voltage mode control method. The
NCP5425 can run from a single supply ranging from 4.6 to 12 V and
support a single two phase or dual single phase outputs. When used as
a dual output controller, the second output tracks voltage transients
from the first. Power blanking for low noise applications is supported
as well as independent cycle−by−cycle current limiting. The part is
available in a 20 pin TSSOP package allowing the designer to
minimize PCB area.
