NCP5425DBR2G Electronic Components

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 mutiple 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 volts 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.
