FAN5182 — Adjustable Output, 1-, 2-, or 3-Phase  
Synchronous Buck Controller  
Features  
Description  
The FAN5182 is  
a
highly efficient, multiphase,  
ƒ
Selectable 1-, 2-, or 3-Phase Operation at up to  
1MHz per Phase  
synchronous buck switching regulator controller  
optimized for converting a 12V main supply into a high-  
current, low-voltage supply for use in point-of-load (POL)  
applications. It uses a multi-loop PWM architecture to

switching frequency that can be optimized for regulator  
size and efficiency. The phase relationship of the output  
signals can be programmed to provide 1-, 2-, or 3-phase  
operation, allowing for construction of up to three  
complementary, interleaved buck switching stages.
