NCP5424  
Dual Synchronous  
Buck Controller with Input  
Current Sharing  
The NCP5424 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 NCP5424 can also be configured as  
two independent out-of-phase controllers.

Using the NCP5424 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 NCP5424 provides a cycle- to- cycle current limit on  
Controller 2 allowing the system to handle transient overcurrent  
events and a hiccup mode overcurrent protection on Controller 1  
allowing lossless short circuit protection. In addition, the NCP5424  
provides Soft Start, undervoltage lockout, and built-in adaptive FET  
nonoverlap time to prevent shoot through.
