CS5422  
Dual Out−of−Phase  
Synchronous  
Buck Controller  
with Current Limit  
http://onsemi.com  
The CS5422 is a dual Nchannel synchronous buck regulator  
controller. It contains all the circuitry required for two independent  
buck regulators and utilizes the V control method to achieve the  
SO16

fastest possible transient response and best overall regulation, while  
using the least number of external components. The CS5422 features  
outofphase synchronization between the channels, reducing the  
input filter requirement. The CS5422 also provides undervoltage  
lockout, Soft Start, built in adaptive FET nonoverlap and hiccup  
mode overcurrent protection. The part is available in a 16 Lead SO  
Narrow or 24 Lead Fused SO Wide package allowing the designer to  
minimize solution size.
