Current Sharing  
The NCP5424A is a flexible dual N−channel synchronous buck

controller utilizing V  
control for fast transient response and

excellent line and load regulation. This highly versatile controller can  
be configured as a single two phase output converter that draws  
programmable amounts of current from two different input voltages or  
all current from one supply. The NCP5424A can also be configured as  
two independent out−of−phase controllers.

Using the NCP5424A in a current sharing input configuration is  
ideal for applications where more power is required than is available  
from one supply, such as video cards or other plug−in boards. When  
configured as a dual output controller, the output of one controller can  
be divided down and used as the reference for the second controller.  
This tracking capability is useful in applications such as Double Data  
Rate (DDR) Memory power where the termination voltage must track  
VDD.

The NCP5424A provides a cycle−to−cycle current limit allowing  
the system to handle transient overcurrent events. In addition, the  
NCP5424A provides Soft Start, undervoltage lockout, and built−in  
adaptive FET nonoverlap time to prevent shoot through.
