Product Summary
The NCP5425DBR2G 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 NCP5425DBR2G contains all the circuitry required for two independent synchronous dual NFET buck regulators utilizing a feed forward voltage mode control method. The NCP5425DBR2G can run from a single supply ranging from 4.6 to 12V and support a single two phase or dual single phase outputs. The NCP5425DBR2G is available in a 20 pin TSSOP package allowing the designer to minimize PCB area.
